A NSEvent extension for changing event charactters

README.md

This allows you to change the character codes associated with an NSEvent. You may want to do this if you override NSTableView's keyDown: method to support j/k movements.

Usage:

theEvent.eventByChangingKeyToKey(NSUpArrowFunctionKey)

NSEventExtensions.swift

extension NSEvent {
  func eventByChangingKeyToKey(key: Int) -> NSEvent? {
    var char = unichar(key)
    let characterString = NSString(characters: &char, length: 1)

    return NSEvent.keyEventWithType(type,
      location: locationInWindow,
      modifierFlags: modifierFlags,
      timestamp: timestamp,
      windowNumber: windowNumber,
      context: context,
      characters: characterString,
      charactersIgnoringModifiers: characterString,
      isARepeat: ARepeat,
      keyCode: char)
  }
}
