Remove Keyboard Shortcuts

[sapporo]

On Jaguar, I had removed the "Block Pop-Up Windows" keyboard shortcut from Safari (because I accidentally unblocked pop-ups serveral times by hitting Cmd-K) with

write com.apple.Safari NSUserKeyEquivalents -dict-add "Block Pop-Up Windows" nil

Strange enough, on Panther this results in a shortcut mapped to the n key - no modifier key needed (works unless you have a text field selected)! And while this is pretty cool in itself (making shortcuts that need no modifier key), I haven't yet managed to override Safari's standard Cmd-K shortcut with "nothing".

The new keyboard shortcuts preference pane won't help either.

Any ideas anyone?

Cheers,
