Keyboard reference

Every action, exactly as the editor defines it. This page is generated from apps/editor/src/keymap.ts, so it cannot drift from the application — and the application itself carries the same list under 🌣 in the header.

Reading the tables

Applies says when a binding is live: any time, input mode only, or with a particular selection. A binding marked fixed is matched by physical key position or is a system chord — the editor lists it, but it cannot be rebound.

Modifier conventions

Written	Means
shift + s	An uppercase letter binding — hold shift
alt + b	Hold alt (option on macOS)
⌃s	ctrl + s (⌘ on macOS)
⌥1–5	alt + the digits 1 to 5
⊞+	The numeric keypad’s +
1–7	The digit row or the keypad, matched by key position

System chords

These are fixed:

Keys	Action
ctrl + s	Save (ctrl + shift + s = save as)
ctrl + o	Open
ctrl + z	Undo
ctrl + shift + z / ctrl + y	Redo
ctrl + c / ctrl + v	Copy / paste a block
ctrl + + / ctrl + − / ctrl + 0	Zoom in / out / reset
Insert	Toggle note input both ways
esc	Leave input mode, or clear the selection
Delete / Backspace	Turn the caret’s event, or the previous one, into rests
alt + ← / →	Shorten / lengthen the duration
alt + ↑ / ↓	Transpose a step (add shift for an octave)

Rebinding

Open the shortcut editor with 🌣. It lists every action by group with its current keys.

The shortcut editor. An amber key shares its character with another action — legal when contexts separate them, like r for rests (input mode) and repeat barlines (selection).

1. Click a binding.
2. Press the key you want. Letters keep their case, alt is recorded, and shift is explicit for symbols.
3. A duplicate shows an amber warning — battuta lets you do it, but tells you.

Reset all restores the defaults. Overrides are stored per layout in the browser’s local storage, so they survive restarts, and switching layouts switches override sets too.

QWERTY and AZERTY are separate maps

The two layouts have separate defaults, because a single merged map double-books keys: QWERTY’s simile key ' is AZERTY’s unshifted digit-4, which collides with the duration row in input mode. Only the punctuation bindings differ; letters and the physical-key bindings are identical.

Pick your layout in the shortcut editor. Bindings match on the character a key produces, so a rebound key follows your layout rather than a physical position — except for the bindings marked fixed, which are position-matched on purpose so the duration digits and fingering keys work everywhere.
