injectHotkeySequence

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

HotkeySequence | (() => HotkeySequence)

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

callback

HotkeyCallback

Function to call when the sequence is completed

options?

| InjectHotkeySequenceOptions | (() => InjectHotkeySequenceOptions)

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

Returns

void

Example

@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'))
  }
}
