Hotkey Sequence API Reference

injectHotkeySequence

Function: injectHotkeySequence()

ts
function injectHotkeySequence(
   sequence, 
   callback, 
   options): void;
function injectHotkeySequence(
   sequence, 
   callback, 
   options): void;

Defined in: injectHotkeySequence.ts:58

Angular inject-based API for registering a keyboard shortcut sequence (Vim-style).

Allows you to register multi-key sequences like 'g g' or 'd d' that trigger when the full sequence is pressed within a timeout.

Each step may include modifiers. You can chain the same modifier across steps (e.g. Shift+R then Shift+T). Modifier-only keydown events (Shift, Control, Alt, or Meta pressed alone) are ignored while matching—they do not advance the sequence or reset progress.

Parameters

sequence

Array of hotkey strings that form the sequence (or getter function)

HotkeySequence | () => HotkeySequence

callback

HotkeyCallback

Function to call when the sequence is completed

options

Options for the sequence behavior (or getter function). enabled: false still registers the sequence (visible in devtools); only execution is suppressed.

InjectHotkeySequenceOptions | () => InjectHotkeySequenceOptions

Returns

void

Example

ts
@Component({ ... })
export class VimEditorComponent {
  lastSequence = signal<string | null>(null)

  constructor() {
    injectHotkeySequence(['G', 'G'], () => this.lastSequence.set('gg → Go to top'))
    injectHotkeySequence(['D', 'D'], () => this.lastSequence.set('dd → Delete line'))
    injectHotkeySequence(['C', 'I', 'W'], () => this.lastSequence.set('ciw'), { timeout: 500 })
    injectHotkeySequence(['Shift+R', 'Shift+T'], () => this.lastSequence.set('⇧R⇧T'))
  }
}
@Component({ ... })
export class VimEditorComponent {
  lastSequence = signal<string | null>(null)

  constructor() {
    injectHotkeySequence(['G', 'G'], () => this.lastSequence.set('gg → Go to top'))
    injectHotkeySequence(['D', 'D'], () => this.lastSequence.set('dd → Delete line'))
    injectHotkeySequence(['C', 'I', 'W'], () => this.lastSequence.set('ciw'), { timeout: 500 })
    injectHotkeySequence(['Shift+R', 'Shift+T'], () => this.lastSequence.set('⇧R⇧T'))
  }
}
