I recently followed this blog to add a keyboard shortcut to lock the screen:

I assigned the commandL keyboard shortcut to this script. I recently discovered the built-in ctrlshifteject, which is better.
Now I'm trying to remove the commandL shortcut, but it has disappeared from my keyboard shortcuts preferences! The keybinding still works, but it's not listed in keyboard shortcuts, and I do not know how to remove it now.
Does anyone know how? Thanks!
