ally.map.keycode

Map human readable names for event.keyCodes.

Description

// example structure
var map = {
  // Element Focus
  tab: 9,

  // Navigation
  left: 37,
  up: 38,
  // ...
  home: 36,

  // Action
  enter: 13,
  escape: 27,
  space: 32,

  // Function keys
  f1: 112,
  // ...

  // Numeric keys
  0: 48,
  1: 49,
  // ...
  'num-0': 96,
  'num-1': 97,
  // ...

  // Latin characters
  a: 65,
  // ...
  z: 90,
};

The map knows the following keys:

• a - z
• 0 - 9
• num-0 - num-9 (number block)
• f1 - f25 (function keys)
• down, left, right, up (arrow keys)
• end, home, pageDown, page-down, pageUp, page-up
• enter, escape, space, tab
• alt, capsLock, caps-lock, ctrl, meta, shift
• pause, insert, delete, backspace

Usage

console.log('keycode of enter', ally.map.keycode.enter);

Changes

• v1.1.0 replaced the key command by meta.
• v1.1.0 added a - z, 0 - 9, num-0 - num-9, f13 - f25, page-down, page-up, caps-lock.
• v1.1.0 added _alias to resolve multiple keyCodes for the same logical key.

Notes

• NOTE: The key meta is known by different keyCodes: 91, 92, 93, 224 - which ally.map.keycodes.alias.91 helps to resolve. The same is true for numeric keys (0-9) and their counterparts on the numblock.
