SharpKeys is built as a Registry hack that is used to make certain keys on a keyboard act like other keys.

For example, if you accidentally hit Caps Lock often, you could use this utility to map Caps Lock to a Shift key or even turn it off completely.

As it relies on internal support within Windows 2000, Windows XP, or Windows Server 2003, you must be running one of these OS's for this Registry hack to work.
