The only time I hit the Caps Lock key is by accident. Well, the only time I used to hit that key was by accident.

After sitting down for a little think, I decided it would be good to remap the key to Enter. With the help of US Netizen's Fix Caps Lock page, I was well on my way.

Adding the above key to HKLM\SYSTEM\CurrentControlSet\Control\Keyboard Layout and rebooting gave me another Enter key. It adds a certain symmetry to the keyboard.

And it still gives me happy jollies every time I hit it on purpose. Synapse-creation ahoy!
