KeyMate is a lightweight and powerful library for managing keyboard shortcuts in web applications. It supports:

• Simple shortcuts (Ctrl + S, Shift + A).
• Key sequences (Ctrl + K, followed by S).
• Group-based management (namespaces) to enable or disable sets of shortcuts dynamically.

• 📜 Simple Shortcuts: Configure combinations like Ctrl + S or Shift + Alt + R.
• 🔗 Key Sequences: Detect successive combinations like Ctrl + K > S.
• 🏷 Group Management: Dynamically enable or disable groups of shortcuts.
• ⚡️ Optimized: Centralized event management for maximum performance.

Install KeyMate using npm or yarn:

npm install keymate

import KeyMate from 'keymate';

const keymate = new KeyMate();

keymate.registerShortcut('global', { ctrl: true, key: 's' }, (event) => {
  console.log('Save triggered!');
});

keymate.registerSequence('global', [
  { ctrl: true, key: 'k' },
  { key: 's' }
], (event) => {
  console.log('Sequence Ctrl + K > S triggered!');
});

keymate.toggleGroup('global', false); // Disable all shortcuts in the "global" group
keymate.toggleGroup('global', true);  // Re-enable the "global" group

• Remove a specific shortcut:

keymate.unregisterShortcut('global', { ctrl: true, key: 's' });

• Remove all shortcuts in a group:

keymate.unregisterShortcut('global');

• group: The namespace or context for the shortcut.
• combination: An object describing the key combination ({ ctrl: boolean, shift: boolean, alt: boolean, key: string }).
• callback: Function to execute when the shortcut is triggered.

• group: The namespace for the sequence.
• combination[]: An array of objects describing a sequence of key combinations.
• callback: Function to execute when the sequence is completed.

• group: The namespace of the shortcuts.
• combination (optional): The specific combination or sequence to remove. If not provided, all shortcuts in the group will be removed.

• group: The namespace of the shortcuts.
• enabled: A boolean to enable or disable the group.

• Returns an array containing all registered shortcuts across all groups.

keymate.registerSequence('editor', [
  { key: 'g' },
  { key: 'o' },
  { key: 't' }
], () => {
  console.log('Sequence "G > O > T" triggered!');
});

For example, activating shortcuts only within a modal:

const modalActive = true;

keymate.registerShortcut('modal', { key: 'Escape' }, () => {
  if (modalActive) {
    console.log('Modal closed!');
  }
});

keymate.toggleGroup('modal', modalActive);

1. Advanced Sequence Management:

   • Add pause/resume functionality for sequences using TimePulse to manage delays precisely.

2. Dynamic Contextual Shortcuts:

   • Enable/disable shortcuts dynamically based on specific elements in the DOM.

3. Inspection API:

   • Add a method to list and debug all active shortcuts with their group and context.

4. Conflict Management:

   • Automatically detect and resolve shortcut conflicts within the same group.

5. Mobile Support:

   • Add support for gestures or keyboard shortcuts specific to mobile keyboards.
