Anybody have any idea how to turn numlock on/off?

Right now my logitech keyboard is stuck in a state where pressing numbers on the number pad results in cursor movement - or worse, freezes in the frontmost app if I touch a certain key (I think it’s the enter key, but it may be the return key).

Gahhhh!!!!

Any help would be appreciated.

Update: I fiddled, fooled, reinstalled drivers.. then turned off “Use Number Pad for Movement” in BBEdit. It works fine now.
