/**
 * Returns the keystroke stored at the given resourcebundle key.

 * The keystroke will be composed of a simple key press and a keystroke mask pattern. The pattern should be specified
 * via the words "shift", "alt", "ctrl", "meta" or "menu". Menu should be used to reference the platform specific menu
 * shortcut. For the sake of safety, menu should only be combined with "shift" and/or "alt" for menu keystrokes.
 * <p/>
 * The keystrokes character key should be either the symbolic name of one of the KeyEvent.VK_* constants or the
 * character for that key.
 * <p/>
 * For the 'A' key, the resource bundle would therefore either contain "VK_A" or "a".
