Keyboard Shortcuts

When using a screen reader, first switch it to focus or forms mode so individual keys reach the game, then press Z from the game screen to focus the board. Except for Z, the shortcuts below work while the board has focus.

These commands operate JustGammon’s virtual board cursor in direct keyboard mode. For touch-screen exploration and standard desktop web navigation, see Accessibility.

Tip

Press letter keys without Shift unless the shortcut explicitly includes it. Shifted shortcuts are case-sensitive and perform different actions from their unshifted keys.

The Result column explains how JustGammon responds:

• Action performs a game or navigation command.
• Screen-reader announcement provides spoken feedback through the accessibility live region without displaying a visible toast.
• Information toast displays a visible informational message intended for all players.
• Dialog opens the corresponding interface.

Screen-reader use

Your screen reader must pass these keys through to the board. See Accessibility for common commands to switch interaction modes.

Press V to temporarily disable or enable JustGammon’s screen-reader announcements. This does not turn the screen reader itself off or change the saved Screen Reader Mode setting. The temporary state resets when you leave the game.
