Keybindings

All keyboard shortcuts can be customized via ~/.prime/agent/keybindings.json. Each action can be bound to one or more keys.

The config file uses the same namespaced keybinding ids that Prime Agent uses internally and that extension authors use in keyHint() and injected keybindings managers.

Older configs using pre-namespaced ids such as cursorUp or expandTools are migrated automatically to the namespaced ids on startup.

After editing keybindings.json, run /reload in Prime Agent to apply the changes without restarting the session.

Key Format

modifier+key where modifiers are ctrl, shift, alt (combinable) and keys are:

• Letters: a-z
• Digits: 0-9
• Special: escape, esc, enter, return, tab, space, backspace, delete, insert, clear, home, end, pageUp, pageDown, up, down, left, right
• Function: f1-f12
• Symbols: `, -, =, [, ], \, ;, ', ,, ., /, !, @, #, $, %, ^, &, *, (, ), _, +, |, ~, {, }, :, <, >, ?

Modifier combinations: ctrl+shift+x, alt+ctrl+x, ctrl+shift+alt+x, ctrl+1, etc.

Custom Configuration

Create ~/.prime/agent/keybindings.json:

{
  "tui.editor.cursorUp": ["up", "ctrl+p"],
  "tui.editor.cursorDown": ["down", "ctrl+n"],
  "tui.editor.deleteWordBackward": ["ctrl+w", "alt+backspace"]
}

Each action can have a single key or an array of keys. User config overrides defaults.

On native Windows, app.suspend has no default binding because Windows terminals do not support Unix job control. If you bind it manually, Prime Agent shows a status message instead of suspending. In WSL, the normal Linux ctrl+z/fg behavior still applies.

Emacs Example

Binding ctrl+p below releases the conflicting app.messages.expand default; shortcuts in other views keep their defaults.

{
  "tui.editor.cursorUp": ["up", "ctrl+p"],
  "tui.editor.cursorDown": ["down", "ctrl+n"],
  "tui.editor.cursorLeft": ["left", "ctrl+b"],
  "tui.editor.cursorRight": ["right", "ctrl+f"],
  "tui.editor.cursorWordLeft": ["alt+left", "alt+b"],
  "tui.editor.cursorWordRight": ["alt+right", "alt+f"],
  "tui.editor.deleteCharForward": ["delete", "ctrl+d"],
  "tui.editor.deleteCharBackward": ["backspace", "ctrl+h"],
  "tui.input.newLine": ["shift+enter", "ctrl+j"]
}

Vim Example

{
  "tui.editor.cursorUp": ["up", "alt+k"],
  "tui.editor.cursorDown": ["down", "alt+j"],
  "tui.editor.cursorLeft": ["left", "alt+h"],
  "tui.editor.cursorRight": ["right", "alt+l"],
  "tui.editor.cursorWordLeft": ["alt+left", "alt+b"],
  "tui.editor.cursorWordRight": ["alt+right", "alt+w"]
}
