10. Keyboard shortcuts

This table is generated from src/ui/shortcuts.ts — the same ALL_SHORTCUTS table the app matches keystrokes against, and the same one the in-app Help panel renders. tests/shortcuts.test.mjs asserts that nothing in it is left unbound and that every chrome combo is reachable; tests/helpPanel.test.mjs asserts the Help panel is generated from it rather than transcribed.

mod is Ctrl on Windows and Linux, ⌘ on macOS.

Notes#

Ctrl/⌘ + prints oddly on macOS. displayCombo('mod++', true) renders as ⌘ with the + lost, in this table and in the Help panel. The binding itself is fine.
The Bound in column is not trivia: it says which module owns the key, so a shortcut that stops working can be traced to one file. Shell handles the chrome, Canvas handles everything that edits the document (so the two never fight over a keystroke), and the view, style and AI features bind their own.
Modifier-free keys are ignored inside text fields, the inline label editor and the command palette, so typing c in a search box does not switch tools.
Ctrl/⌘ V only calls preventDefault() when the in-app clipboard has something; with it empty, the native paste event is allowed through so a foreign diagram on the system clipboard can be imported.
? and F1 both open the Help panel. They are bound by src/ui/helpFeature.ts and are deliberately not in ALL_SHORTCUTS, so they do not appear in the table above or in the Help panel's own list — that table is owned by the chrome and the help feature only reads it.
Two toolbar tooltips advertise a key the app does not bind: the rulers button says ⇧R when the real binding is Alt R. Use the table above.
