Lazy implementation

Lazy implementation: the browser fires these events whenever the user presses the Cut, Copy, or Paste shortcut keys, whether that action makes sense in a given context or not.

For instance, when you press [Ctrl | Cmd]+X while the focus is nowhere in particular and you have not selected any text, some browsers will fire a cut event, even though there's nothing to cut.

This is a very odd bug, in that it’s an old one in Firefox but solved in FF4, but new in Safari and Chrome. Safari 3 and Chrome 1 did not have this bug and implemented the events correctly, but newer versions do have the bug.
