 19// Text field for capturing hot key entry. This is intended to be similar to the
 20// Apple key editor in their Keyboard pref pane.
 21
 22// NOTE: There are strings that need to be localized to use this field.  See the
 23// code in stringForKeycode the the keys.  The keys are all the English versions
 24// so you'll get reasonable things if you don't have a strings file.

 51//  Notes:
 52//  - Though you are free to implement control:textShouldEndEditing: in your
 53//    delegate its return is always ignored. The field always accepts only
 54//    one hotkey keystroke before editing ends.
 55//  - The "value" binding of this control is to the dictionary describing the
 56//    hotkey.
 57//  - The field does not attempt to consume all hotkeys. Hotkeys which are
 58//    already bound in Apple prefs or other applications will have their
 59//    normal effect.
