Keyboard shortcuts - Koharu

Tool and editing shortcuts apply while a project is open and an input, textarea, or editable text region is not focused.

Tools

Tool	Key
Select	`V`
Text	`T`
Brush	`B`
Eraser	`E`
Color picker	`I`
Remove	`J`
Pan	`H`
Fit Window	`0`

Change tool characters in Settings → Shortcuts.

Action	Gesture
Pan temporarily	Hold `Space` or the middle button and drag
Pan	Scroll; `Shift` + scroll pans horizontally
Zoom at the pointer	`Ctrl` + scroll
Change brush diameter	`Alt` + scroll with Brush, Eraser, or Remove
Cancel gesture and clear selection	`Escape`
Fit the active page	`0` by default

The active tool does not change while Space is held. Switching away from Koharu cancels an unfinished canvas gesture.

Editing

Action	Windows / Linux	macOS
Undo	`Ctrl+Z`	`Command+Z`
Redo	`Ctrl+Shift+Z`	`Command+Shift+Z`
Select all editable page layers	`Ctrl+A`	`Command+A`
Delete selected layers	`Delete` or `Backspace`	`Delete` or `Backspace`

Use a unique character for each tool. If bindings conflict, the Fit Window key is checked first, then the first matching tool in toolbar order wins. Custom bindings reset when Koharu restarts.

Shortcuts affect the desktop interface, not the exported page.
