Remap that pesky enter key

That pesky little enter key next to the right command key is quite useless. Apple has even come to the realization this wasted key with the latest versions of their MacBook (Pro) keyboard layouts.

Bring in Double Command. With this free preference pane, that useless enter key can now be something useful, such as a second option key, or my personal preference, a second control key for the ease of changing spaces with one hand.
