TUI Keymap Action Matrix

This file defines the supported keymap actions and their current default bindings. For runtime behavior, safety invariants, and testing guidance, see docs/tui-keymap.md.

Preset behavior

• latest is an alias to the newest shipped preset.
• Today, latest -> v5.
• To keep stable behavior over time, pin preset = "v1".

Precedence

1. tui.keymap.<context>.<action>
2. tui.keymap.global.<action> (chat/composer fallback actions only)
3. Preset default (v5 today)

Default v1 Compatibility Notes

• Some actions intentionally ship with multiple bindings for the same logical shortcut because terminals differ in modifier reporting.
• Today this includes:
  • composer.toggle_shortcuts: ? and shift-?
  • approval.open_fullscreen: ctrl-a and ctrl-shift-a
  • onboarding.toggle_animation: ctrl-. and ctrl-shift-.
• Shifted letter bindings are also matched compatibly across terminal variants when reported as uppercase letters without explicit SHIFT (for example shift-i matching I, shift-a matching A, and shift-o matching O).
• Keep these paired defaults unless/until key-event normalization is made platform-consistent at a lower layer.
