You can also clean up your Command List by opening it (typing list as a keyword) and click File > Verify Targets Exist. This will let you quickly delete keywords that lead to nonexistent programs.
That is a nice feature, but perhaps you can add a "
Yes to all" button because I had to click Yes ~ 100 times to remove all the dead items in my list

.
[new feature idea 1]Also strangely I had to repeat the File > Verify Targets Exist several times (about 10) before all dead links were really gone, every time it found less items to delete but still, again a bit of a hassle. I must say though Keybreeze determined quite rapidly which files didn't exist ... so if the user wanted it could even be done periodically (at each startup)
[new feature idea 2]What would also be nice is (in the case of moved shortcuts in the Start Menu for instance) to automatically determine the location of the (moved) shortcut and restore the command.
