Inverts your view of the chess board for the duration of the
-current game. Starting a new game returns the board to normal.
-The v key is a keyboard equivalent.
-
Adjudications
Pops up a sub-menu where you can enable or disable various adjudications
-that XBoard can perform in engine-engine games.
-You can instruct XBoard to detect and terminate the game on checkmate
-or stalemate, even if the engines would not do so, to verify engine
-result claims (forfeiting engines that make false claims), rather than
-naively following the engine, to declare draw on posititions
-which can never be won for lack of mating material, (e.g. KBK),
-or which are impossble to win unless the opponent seeks its own demise
-(e.g. KBKN).
-For these adjudications to work, ‘Test Legality’ should be switched on.
-It is also possible to insruct XBoard to enforce a 50-move or 3-fold-repeat
-rule and automtically declare draw (after a user-adjustable number of moves
-or repeats) even if the engines are prepared to go on.
-It is also possible to have XBoard declare draw on games that seem to drag on
-forever, or adjudicate a loss if both engines agree (for 3 cosecutive moves) that one
-of them is behind more than a user-adjustable score threshold.
-For the latter adjudication to work, XBoard should be able to properly understand
-the engine's scores. To faclitate the latter, you can inform xboard here if
-the engines report scores from the viewpoint of white, or from that of their own color.
-
Engine Settings
Pops up a sub-menu where you can set some engine parameters common to most engines,
-such as hash-table size, tablebase cache size, maximum number of processors
-that SMP engines can use, and where to find the Polyglot adapter needed
-to run UCI engines under XBoard. The feature tht allows setting of these parameters on
-engines is new since XBoard 4.3.15, so not many WinBoard engines respond
-to it yet, but UCI engines should.
-It is also possible to specify a GUI opening book here, i.e. an opening
-book that XBoard consults for any position a playing engine gets in.
-It then forces the engine to play the book move, rather than to think up its own,
-if that position is found in the book.
-The book can switched on and off independently for either engine.
-
Time Control
Pops up a sub-menu where you can set the time-control parameters interactively.
-Allows you to select classical or incremental time controls,
-set the moves per session, session duration, and time increment.
-Also allows specification of time-odds factors for one or both engines.
-If an engine is given a time-odds factor N, all time quota it gets,
-be it at the beginning of a session or through the time increment or
-fixed time per move, will be divided by N.
-
Always Queen
If this option is off, XBoard brings up a dialog
-box whenever you move a pawn to the last rank, asking what piece
-you want to promote it to. If the option is true, your pawns are
-always promoted to queens. Your opponent can still underpromote.
-
Animate Dragging
If Animate Dragging is on, while you are dragging a piece with the
-mouse, an image of the piece follows the mouse cursor.
-If Animate Dragging is off, there is no visual feedback while you are
-dragging a piece, but if Animate Moving is on, the move will be
-animated when it is complete.
-
Animate Moving
If Animate Moving is on, all piece moves are animated. An image of the
-piece is shown moving from the old square to the new square when the
-move is completed (unless the move was already animated by Animate Dragging).
-If Animate Moving is off, a moved piece instantly disappears from its
-old square and reappears on its new square when the move is complete.
-
Auto Comment
If this option is on, any remarks made on ICS while you are observing or
-playing a game are recorded as a comment on the current move. This includes
-remarks made with the ICS commands say, tell, whisper,
-and kibitz.
-Limitation: remarks that you type yourself are not recognized;
-XBoard scans only the output from ICS, not the input you type to it.
-
Auto Flag
If this option is on and one player runs out of time
-before the other,
-XBoard
-will automatically call his flag, claiming a win on time.
-In ICS mode, Auto Flag will only call your opponent's flag, not yours,
-and the ICS may award you a draw instead of a win if you have
-insufficient mating material. In local chess engine mode,
-XBoard
-may call either player's flag and will not take material into account.
-
Auto Flip View
If the Auto Flip View option is on when you start a game, the board
-will be automatically oriented so that your pawns move from the bottom
-of the window towards the top.
-
Auto Observe
If this option is on and you add a player to your gnotify
-list on ICS, XBoard will automatically observe all of that
-player's games, unless you are doing something else (such as
-observing or playing a game of your own) when one starts.
-The games are displayed
-from the point of view of the player on your gnotify list; that is, his
-pawns move from the bottom of the window towards the top.
-Exceptions: If both players in a game are on your gnotify list, if
-your ICS
-highlight
-variable is set to 0, or if the ICS you are using does not
-properly support observing from Black's point of view,
-you will see the game from White's point of view.
-
Auto Raise Board
If this option is on, whenever a new game begins, the chessboard window
-is deiconized (if necessary) and raised to the top of the stack of windows.
-
Auto Save
If this option is true, at the end of every game XBoard prompts
-you for a file name and appends a record of the game to the file
-you specify.
-Disabled if the saveGameFile command-line
-option is set, as in that case all games are saved to the specified file.
-See Load and Save options.
-
Blindfold
If this option is on, XBoard displays the board as usual but does
-not display pieces or move highlights. You can still move in the
-usual way (with the mouse or by typing moves in ICS mode), even though
-the pieces are invisible.
-
Flash Moves
If this option is on, whenever a move is completed, the moved piece flashes.
-The number of times to flash is set by the flashCount command-line
-option; it defaults to 3 if Flash Moves is first turned on from the menu.
-
-If you are playing a game on an ICS, the board is always
-oriented at the start of the game so that your pawns move from
-the bottom of the window towards the top. Otherwise, the starting
-orientation is determined by the flipView command line option;
-if it is false (the default), White's pawns move from bottom to top
-at the start of each game; if it is true, Black's pawns move from
-bottom to top. See User interface options.
-
Get Move List
If this option is on, whenever XBoard
-receives the first board of a new ICS game (or a different game from
-the one it is currently displaying), it
-retrieves the list of past moves from the ICS.
-You can then review the moves with the ‘Forward’ and ‘Backward’
-commands
-or save them with ‘Save Game’. You might want to
-turn off this option if you are observing several blitz games at once,
-to keep from wasting time and network bandwidth fetching the move lists over
-and over.
-When you turn this option on from the menu, XBoard
-immediately fetches the move list of the current game (if any).
-
Highlight Last Move
If Highlight Last Move is on, after a move is made, the starting and
-ending squares remain highlighted. In addition, after you use Backward
-or Back to Start, the starting and ending squares of the last move to
-be unmade are highlighted.
-
Move Sound
If this option is on, XBoard alerts you by playing a sound
-after each of your opponent's moves (or after every
-move if you are observing a game on the Internet Chess Server).
-The sound is not played after moves you make or moves read from a
-saved game file. By default, the
-sound is the terminal bell, but on some systems you can change it
-to a sound file using the soundMove option; see below.
-
-If you turn on this option when using XBoard with the Internet
-Chess Server, you will probably want to give the
-set bell 0
-command to the ICS, since otherwise the ICS will ring the terminal bell
-after every move (not just yours). (The .icsrc file
-is a good place for this; see ICS options.)
-
ICS Alarm
When this option is on, an alarm sound is played when your clock
-counts down to the icsAlarmTime (by default, 5 seconds) in an ICS
-game. For games with time controls that include an increment, the
-alarm will sound each time the clock counts down to the icsAlarmTime.
-By default, the alarm sound is the terminal bell, but on some systems
-you can change it to a sound file using the soundIcsAlarm option; see
-below.
-
Old Save Style
If this option is off, XBoard saves games in PGN
-(portable game notation) and positions in FEN (Forsythe-Edwards
-notation). If the option is on, a save style that is compatible
-with older versions of XBoard is used instead.
-The old position style is more human-readable
-than FEN; the old game style has no particular advantages.
-
Periodic Updates
If this option is off (or if
-you are using a chess engine that does not support periodic updates),
-the analysis window
-will only be updated when the analysis changes. If this option is
-on, the Analysis Window will be updated every two seconds.
-
Ponder Next Move
If this option is off, the chess engine will think only when it is on
-move. If the option is on, the engine will also think while waiting
-for you to make your move.
-
Popup Exit Message
If this option is on, when XBoard wants to display a message just
-before exiting, it brings up a modal dialog box and waits for you to
-click OK before exiting. If the option is off, XBoard prints the
-message to standard error (the terminal) and exits immediately.
-
Popup Move Errors
If this option is off, when you make an error in moving (such as
-attempting an illegal move or moving the wrong color piece), the
-error message is displayed in the message area. If the option is
-on, move errors are displayed in small popup windows like other errors.
-You can dismiss an error popup either by clicking its OK button or by
-clicking anywhere on the board, including downclicking to start a move.
-
Premove
If this option is on while playing a game on an ICS, you can register
-your next planned move before it is your turn. Move the piece with
-the mouse in the ordinary way, and the starting and ending squares
-will be highlighted with a special color (red by default). When it is
-your turn, if your registered move is legal, XBoard will send it to
-ICS immediately; if not, it will be ignored and you can make a
-different move. If you change your mind about your premove, either
-make a different move, or double-click on any piece to cancel the move
-entirely.
-
Quiet Play
If this option is on, XBoard will automatically issue an ICS
-set shout 0
-command whenever you start a game and a
-set shout 1
-command whenever you finish one. Thus, you will not be distracted
-by shouts from other ICS users while playing.
-
Show Coords
If this option is on, XBoard displays algebraic coordinates
-along the board's left and bottom edges.
-
Hide Thinking
If this option is off, the chess engine's notion of the score and best
-line of play from the current position is displayed as it is
-thinking. The score indicates how many pawns ahead (or if negative,
-behind) the chess engine thinks it is. In matches between two
-machines, the score is prefixed by ‘W’ or ‘B’ to indicate
-whether it is showing White's thinking or Black's, and only the thinking
-of the engine that is on move is shown.
-
Test Legality
If this option is on, XBoard tests whether the moves you try to make
-with the mouse are legal and refuses to let you make an illegal move.
-Moves loaded from a file with ‘Load Game’ are also checked. If
-the option is off, all moves are accepted, but if a local chess engine
-or the ICS is active, they will still reject illegal moves. Turning
-off this option is useful if you are playing a chess variant with
-rules that XBoard does not understand. (Bughouse, suicide, and wild
-variants where the king may castle after starting on the d file are
-generally supported with Test Legality on.)
+
Time Control
Pops up a sub-menu where you can set the time-control parameters interactively.
+Allows you to select classical or incremental time controls,
+set the moves per session, session duration, and time increment.
+Also allows specification of time-odds factors for one or both engines.
+If an engine is given a time-odds factor N, all time quota it gets,
+be it at the beginning of a session or through the time increment or
+fixed time per move, will be divided by N.
+The shifted Alt+T key is a keyboard equivalent.
+
Common Engine
Pops up a sub-menu where you can set some engine parameters common to most engines,
+such as hash-table size, tablebase cache size, maximum number of processors
+that SMP engines can use, and where to find the Polyglot adapter needed
+to run UCI engines under XBoard. The feature that allows setting of these parameters on
+engines is new since XBoard 4.3.15, so not many XBoard/WinBoard engines respond
+to it yet, but UCI engines should.
+
+
It is also possible to specify a GUI opening book here, i.e. an opening
+book that XBoard consults for any position a playing engine gets in.
+It then forces the engine to play the book move, rather than to think up its own,
+if that position is found in the book.
+The book can switched on and off independently for either engine.
+The way book moves are chosen can be influenced through the settings of
+book depth and variety.
+After both sides have played more moves than the specified depth,
+the book will no longer be consulted.
+When the variety is set to 50, moves will be played with the probability
+specified in the book.
+When set to 0, only the move(s) with the highest probability will be played.
+When set to 100, all listed moves will be played with equal pobability.
+Other settings interpolate between that.
+The shifted Alt+U key is a keyboard equivalent.
+
Adjudications
Pops up a sub-menu where you can enable or disable various adjudications
+that XBoard can perform in engine-engine games.
+The shifted Alt+J key is a keyboard equivalent.
+You can instruct XBoard to detect and terminate the game on checkmate
+or stalemate, even if the engines would not do so, to verify engine
+result claims (forfeiting engines that make false claims), rather than
+naively following the engine, to declare draw on positions
+which can never be won for lack of mating material, (e.g. KBK),
+or which are impossible to win unless the opponent seeks its own demise
+(e.g. KBKN).
+For these adjudications to work, ‘Test Legality’ should be switched on.
+It is also possible to instruct XBoard to enforce a 50-move or 3-fold-repeat
+rule and automatically declare draw (after a user-adjustable number of moves
+or repeats) even if the engines are prepared to go on.
+It is also possible to have XBoard declare draw on games that seem to drag on
+forever, or adjudicate a loss if both engines agree (for 3 consecutive moves) that one
+of them is behind more than a user-adjustable score threshold.
+For the latter adjudication to work, XBoard should be able to properly understand
+the engine's scores. To facilitate the latter, you can inform xboard here if
+the engines report scores from the viewpoint of white, or from that of their own color.
+
Match Game Options
Summons a dialog where you can set options important for playing automatic
+matches between two chess programs
+(e.g. by using the ‘Machine Match’ menu item in the ‘Mode’ menu).
+You can specify the number of games such a match should last,
+and the duration of the pause between games
+(important for some older engines to not have the last move of a previous
+game be given when the next game has already started).
+You can also specify a file with opening lines, or a file with initial positions
+(the loadGameFile and loadPositionFile options),
+and the number of the game or position to use from these files.
+Values -1 and -2 of this 'index' convey a special meaning,
+namely that XBoard should automatically step through all lines or positions
+in these files.
+With -1 such stepping is done every game; with -2 every two games,
+so that each line or position is played with both colors before stepping
+to the next one.
+You can have XBoard automatically rewind to the first line or position
+in the file after the index reaches a certain vaue,
+which you can also specify here.
+
Load Game Options
Summons a dialog where you can set the autoDisplayComment and
+autoDisplayTags options, (which control popups when viewing loaded games),
+and specify the rate at which loaded games are auto-played,
+in seconds per move (which can be a fractional number, like 1.6).
+
Save Game Options
Summons a dialog where you can specify the files on which XBoard should
+automtically save any played or entered games,
+(the saveGameFile option),
+or the final position of such games (the savePositionfile option).
+You can also select 'auto-save' without a file name,
+in which case XBoard will prompt the user for a file name after each game.
+You can also set the default value for the PGN Event tag that will
+be used for each new game you start.
+Various options for the format of the game can be specified as well,
+such as whether scores and depths of engine games should be saved as comments,
+and if a tag with info about the score with which the engine came out of book
+should be included.
+For Chess, always set the format to PGN, rather than "old save stye"!
+
Game List
Pops up a dialog where you can select the PGN tags that should appear
+on the lines in the game list, and their order.
+
Sound Options
Summons a dialog where you can specify the sounds that should accompany
+various events that can occur XBoard.
+Most events are only relevant to ICS play,
+but the move sound is an important exception.
+For each event listed in the dialog,
+you can select a standard sound from a menu.
+You can also select a user-supplied sound file,
+by typing its name into the designated text-edit field first,
+and then selecting "Above WAV File" from the menu for the event.
+A dummy event has been provided for trying out the sounds with the
+"play" button next to it.
+The directory with standard sounds, and the external program for playing
+the sounds can be specified too, but normally you would not touch these
+once XBoard is properly installed.
+
Move Sound
When a move sound other than 'None' is selected,
+XBoard alerts you by playing a sound
+after each of your opponent's moves (or after every
+move if you are observing a game on the Internet Chess Server).
+The sound is not played after moves you make or moves read from a
+saved game file.
+If you turn on this option when using XBoard with the Internet
+Chess Server, you will probably want to give the
+set bell 0
+command to the ICS, since otherwise the ICS will ring the terminal bell
+after every move (not just yours). (The .icsrc file
+is a good place for this; see ICS options.)
+
General Options
The following items to set option values appear in the dialog
+summoned by the general Options menu item.
+
Always Queen
If this option is off, XBoard brings up a dialog
+box whenever you move a pawn to the last rank, asking what piece
+you want to promote it to. If the option is true, your pawns are
+always promoted to queens. Your opponent can still under-promote.
+The shifted Ctrl-Q key is a keyboard equivalent.
+
Animate Dragging
If Animate Dragging is on, while you are dragging a piece with the
+mouse, an image of the piece follows the mouse cursor.
+If Animate Dragging is off, there is no visual feedback while you are
+dragging a piece, but if Animate Moving is on, the move will be
+animated when it is complete.
+
Animate Moving
If Animate Moving is on, all piece moves are animated. An image of the
+piece is shown moving from the old square to the new square when the
+move is completed (unless the move was already animated by Animate Dragging).
+If Animate Moving is off, a moved piece instantly disappears from its
+old square and reappears on its new square when the move is complete.
+The shifted Ctrl-A key is a keyboard equivalent.
+
Auto Flag
If this option is on and one player runs out of time
+before the other,
+XBoard
+will automatically call his flag, claiming a win on time.
+The shifted Ctrl-F key is a keyboard equivalent.
+In ICS mode, Auto Flag will only call your opponent's flag, not yours,
+and the ICS may award you a draw instead of a win if you have
+insufficient mating material. In local chess engine mode,
+XBoard
+may call either player's flag and will not take material into account (?).
+
Auto Flip View
If the Auto Flip View option is on when you start a game, the board
+will be automatically oriented so that your pawns move from the bottom
+of the window towards the top.
+
+
If you are playing a game on an ICS, the board is always
+oriented at the start of the game so that your pawns move from
+the bottom of the window towards the top. Otherwise, the starting
+orientation is determined by the flipView command line option;
+if it is false (the default), White's pawns move from bottom to top
+at the start of each game; if it is true, Black's pawns move from
+bottom to top. See User interface options.
+
Blindfold
If this option is on, XBoard displays the board as usual but does
+not display pieces or move highlights. You can still move in the
+usual way (with the mouse or by typing moves in ICS mode), even though
+the pieces are invisible.
+
Drop Menu
Controls if right-clicking the board in crazyhouse / bughouse
+will pop up a menu to drop a piece on the clicked square
+(old, deprecated behavior)
+or allow you to step through an engine PV
+(new, recommended behavior).
+
Highlight Dragging
If Highlight Dragging is on, and the option -showTargetSquares is also on
+in the settings file, all squares a piece that is 'picked up' with the mouse
+can legally move to are highighted with a fat colored dot in the
+highlightColor (non-captures) or premoveHighlightColor (captures).
+Legality testing must be on for XBoard to know how the piece moves.
+
Highlight Last Move
If Highlight Last Move is on, after a move is made, the starting and
+ending squares remain highlighted. In addition, after you use Backward
+or Back to Start, the starting and ending squares of the last move to
+be unmade are highlighted.
+
Highlight with Arrow
Causes the highlighting described in Highlight Last Move to be done
+by drawing an arrow between the highlighted squares,
+so that it is visible even when the width of the grid lines is set to zero.
+
One-Click Moving
If this option is on, XBoard does not wait for you to click both the
+from- and the to-square, or drag the piece, but performs a move as soon
+as it is uniqely specified.
+This applies to clicking an own piece that only has a single legal move,
+clicking an empty square or opponent piece where only one of your pieces
+can move (or capture) to.
+Furthermore, a double-click on a piece that can only make a single capture
+will cause that capture to be made.
+Promoting a Pawn by clicking its to-square will suppress the promotion
+popup, and make it promote to Queen.
+
Periodic Updates
If this option is off (or if
+you are using a chess engine that does not support periodic updates),
+the analysis window
+will only be updated when the analysis changes. If this option is
+on, the Analysis Window will be updated every two seconds.
+
Ponder Next Move
If this option is off, the chess engine will think only when it is on
+move. If the option is on, the engine will also think while waiting
+for you to make your move.
+The shifted Ctrl-P key is a keyboard equivalent.
+
Popup Exit Message
If this option is on, when XBoard wants to display a message just
+before exiting, it brings up a modal dialog box and waits for you to
+click OK before exiting. If the option is off, XBoard prints the
+message to standard error (the terminal) and exits immediately.
+
Popup Move Errors
If this option is off, when you make an error in moving (such as
+attempting an illegal move or moving the wrong color piece), the
+error message is displayed in the message area. If the option is
+on, move errors are displayed in small pop-up windows like other errors.
+You can dismiss an error pop-up either by clicking its OK button or by
+clicking anywhere on the board, including down-clicking to start a move.
+
Show Coords
If this option is on, XBoard displays algebraic coordinates
+along the board's left and bottom edges.
+
Hide Thinking
If this option is off, the chess engine's notion of the score and best
+line of play from the current position is displayed as it is
+thinking. The score indicates how many pawns ahead (or if negative,
+behind) the chess engine thinks it is. In matches between two
+machines, the score is prefixed by ‘W’ or ‘B’ to indicate
+whether it is showing White's thinking or Black's, and only the thinking
+of the engine that is on move is shown.
+The shifted Ctrl-H key is a keyboard equivalent.
+
Test Legality
If this option is on, XBoard tests whether the moves you try to make
+with the mouse are legal and refuses to let you make an illegal move.
+The shifted Ctrl-L key is a keyboard equivalent.
+Moves loaded from a file with ‘Load Game’ are also checked. If
+the option is off, all moves are accepted, but if a local chess engine
+or the ICS is active, they will still reject illegal moves. Turning
+off this option is useful if you are playing a chess variant with
+rules that XBoard does not understand. (Bughouse, suicide, and wild
+variants where the king may castle after starting on the d file are
+generally supported with Test Legality on.)
+
Flash Moves
Flash Rate
If this option is non-zero, whenever a move is completed,
+the moved piece flashes the specified number of times.
+The flash-rate setting determines how rapidly this flashing occurs.
+
Animation Speed
Determines the duration (in msec) of an animation step,
+when ‘Animate Moving’ is swiched on.
+
+
ICS Options
The following options occur in a dialog summoned by the
+ICS Options menu item.
+
Auto Kibitz
Setting this option when playingwith or aginst a chess program on an ICS
+will cause the last line of thinking output of the engine before its move
+to be sent to the ICS in a kibitz command.
+In addition, any kibitz message received through the ICS from
+an opponent chess program will be diverted to the engine-output window,
+(and suppressed in the console),
+where you can play through its PV by right-clicking it.
+
Auto Comment
If this option is on, any remarks made on ICS while you are observing or
+playing a game are recorded as a comment on the current move. This includes
+remarks made with the ICS commands say, tell, whisper,
+and kibitz.
+Limitation: remarks that you type yourself are not recognized;
+XBoard scans only the output from ICS, not the input you type to it.
+
Auto Observe
If this option is on and you add a player to your gnotify
+list on ICS, XBoard will automatically observe all of that
+player's games, unless you are doing something else (such as
+observing or playing a game of your own) when one starts.
+The games are displayed
+from the point of view of the player on your gnotify list; that is, his
+pawns move from the bottom of the window towards the top.
+Exceptions: If both players in a game are on your gnotify list, if
+your ICS
+highlight
+variable is set to 0, or if the ICS you are using does not
+properly support observing from Black's point of view,
+you will see the game from White's point of view.
+
Auto Raise Board
If this option is on, whenever a new game begins, the chessboard window
+is deiconized (if necessary) and raised to the top of the stack of windows.
+
Auto Save
If this option is true, at the end of every game XBoard prompts
+you for a file name and appends a record of the game to the file
+you specify.
+Disabled if the saveGameFile command-line
+option is set, as in that case all games are saved to the specified file.
+See Load and Save options.
+
Background Observe
Setting this option will make XBoard suppress display of any boards
+from observed games while you are playing.
+In stead the last such board will be remembered,
+and shown to you when you right-click the board.
+This allows you to peek at your bughouse partner's game when you want,
+without disturbing your own game too much.
+
Dual Board
Setting this option in combination with ‘Background Observe’
+will display boards of observed games while you are playing
+on a second board next to that of your own game.
+
Get Move List
If this option is on, whenever XBoard
+receives the first board of a new ICS game (or a different game from
+the one it is currently displaying), it
+retrieves the list of past moves from the ICS.
+You can then review the moves with the ‘Forward’ and ‘Backward’
+commands
+or save them with ‘Save Game’. You might want to
+turn off this option if you are observing several blitz games at once,
+to keep from wasting time and network bandwidth fetching the move lists over
+and over.
+When you turn this option on from the menu, XBoard
+immediately fetches the move list of the current game (if any).
+
Quiet Play
If this option is on, XBoard will automatically issue an ICS
+set shout 0
+command whenever you start a game and a
+set shout 1
+command whenever you finish one. Thus, you will not be distracted
+by shouts from other ICS users while playing.
+
Seek Graph
Setting this option will cause XBoard to display an graph of
+currently active seek ads when you left-click the board
+while idle and logged on to an ICS.
+
Auto-Refresh Seek Graph
In combination with the ‘Seek Graph’ option this

+This only works on FICS and ICS,
+and requires a lot of bandwidth on a busy server.

Premove
Premove White
Premove Black
First White Move
First Black Move
If this option is on while playing a game on an ICS, you can register
+your next planned move before it is your turn. Move the piece with
+the mouse in the ordinary way, and the starting and ending squares
+will be highlighted with a special color (red by default). When it is
+your turn, if your registered move is legal, XBoard will send it to
+ICS immediately; if not, it will be ignored and you can make a
+different move. If you change your mind about your premove, either
+make a different move, or double-click on any piece to cancel the move
+entirely.
+
+
You can also enter premoves for the first white and black moves
+of the game.
+
ICS Alarm
ICS Alarm Time
When this option is on, an alarm sound is played when your clock
+counts down to the icsAlarmTime in an ICS game.
+(By default, the time is 5 seconds, but you can pecify other values
+with the Alarm Time spin control.)
+For games with time controls that include an increment, the
+alarm will sound each time the clock counts down to the icsAlarmTime.
+By default, the alarm sound is the terminal bell, but on some systems
+you can change it to a sound file using the soundIcsAlarm option; see
+below.
+
Colorize Messages
Ticking this options causes various types of ICS messages do be
+displayed with different foreground or background colors in the console.
+The colors can be individually selected for each type,
+through the accompanying text edits.

Save Settings Now
Selecting this menu item causes the current XBoard settings to be
+written to the settings file, so they will also apply in future sessions.
+Note that some settings are 'volatile', and are not saved,
+because XBoard considers it too unlikely that you want those to apply
+next time.
+In particular this applies to the Chess program names, and all options
+giving information on those Chess programs (such as their directory,
+if they have their own opening book, if they are UCI or native XBoard),
+or the variant you are playing.
+Such options would still be understood when they appear in the settings
+file in case they were put there with the aid of a text editor, but they
+would disappear from the file as soon as you save the settings.
+
Save Settings on Exit
Setting this option has no immediate effect, but causes the settings
+to be saved when you quit XBoard. What happens then is otherwise
+identical to what happens when you use select "Save Settings Now",
+see there.
