Keyboard shortcuts

Two families: menu shortcuts (macOS conventions, fixed) and board navigation shortcuts — those remap freely in Settings > Shortcuts. Cmd + ? shows this list inside the app.

Board navigation (customizable)

ShortcutAction
/ Previous / next move — follows the chosen path through variations; at the end of the game, it plays the move of the line followed in Preview
/ Next / previous line within the Preview zone — otherwise, designate a continuation at a fork ( plays it) or switch between sibling lines
J / Shift + JNext / previous mistake
Cmd + → / Cmd + ←Next / previous decisive move
Shift + →The Review on a faulty move — and play out in Preview the continuation designated with /
Shift + ←Step back in the projected line
Tab / Shift + TabNext / previous zone of lines in Preview — engine, review, study, collection… (the zone survives moving through the game)
Option + Tab / Option + Shift + TabNext / previous tree variation — even during a Preview
Option + ↑ / Option + ↓Cycle the hovered engine line
Option + ←Previous branching point — the last position above you that offered more than one move. No effect when there is none left
IHints: the best-move arrow on the board
BClassification badges (?!/?/??) on the piece and in the list
Cmd + Option + + / Cmd + Option + -Text size for moves and lines (also in the View menu, and via “Aa” in the MOVES header)
Cmd + Option + GPlay out the line in Preview — press again to return to the real position, keeping the chosen line
EscapeReturn to the real position; a second Escape releases Preview (and leaves the current mode)

With the mouse, available continuations can also be played by clicking the destination square of their arrow on the board. And for a that pauses at every junction, the Stop at forks option (Settings > Analysis, off by default) opens a menu of continuations: / to choose, or to play, Escape to pass through.

Customizing

Settings > Shortcuts lists every navigation action with its current shortcut: click, press the new combination, done. Reader mode follows the same custom shortcuts.
