keymap-demo

Overview ¶

keymap-demo is the reference interactive demo for the toolkit Action + Keymap layer driven from a terminal. A single toolkit.ActionRegistry and toolkit.Keymap are the one source of truth: the same Actions feed the menu shortcut hints, the command palette, and the keyboard bindings.

It demonstrates, live in the terminal, the four behaviours the layer exists to provide:

• accelerators: Ctrl+S runs "Save" (a modifier chord parsed from the key stream);
• multi-stroke chords: "g" then "d" runs "GoToDef" (the PENDING row shows the half-typed chord between strokes);
• scopes: "a" runs "AllItems" globally, but with the widget scope active (toggled with Tab) it runs "AllText" instead — the widget binding shadows the global one;
• hot rebinding: "r" rebinds "GoToDef" to "z" at run time; the menu hint updates and "z" then runs it.

The screen is a fixed grid of labelled rows so its state is trivially assertable cell-by-cell:
