Minecraft has a hotkey which is activated by command + delete on OSX. This useless hotkey, when activated, deletes entire words when pressing the delete key (and typing things) rather than deleting single letters at a time. This hotkey works as intended, but as of 1.6+ the hotkey is also being activated whenever I alt+tab (command+tab on OSX) to a different window. This results in me tabbing back into MC and trying to type something, pressing backspace because of spelling error or somehing and it deletes entire words. The hotkey can be deactivated by pressing command + delete.

Summary; hotkey command+delete is also being activated when alt tabbing on mac OSX.
