In Mac OS X, how can I disable the Cmd-F1 keyboard shortcut? I use a Macbook Pro, with an external monitor hooked up, and set to extend my display.

I keep accidentally hitting Cmd-F1 when I mean to hit Cmd-1. Cmd-F1 toggles display mirroring. All my windows are then moved into one desktop. When I toggle display mirroring again, everything is mostly fine, except all the windows that were on the other monitor are now all in one, so I have to reorganize everything.

This isn't really that big of a deal, it doesn't take long to organize everything again, but I am really surprised that there isn't an easy way to disable this. Googling has failed me. It seems like every other shortcut is editable/disable-able, except for this one.

Here are few caveats:

1) Please, don't recommend anything related to Spaces. I've tried it, and I can't stand it.

2) This only seems to happen when I am using Fireworks (which is a job requirement.) I've tried remapping the Cmd-1 key, but it never seems to take. I would also consider this problem solved if you can tell me how to successfully remap keyboard shortcuts in fireworks.

3) Is it possible to disable display-mirroring system wide? I can only imagine using it give a presentation, and I don't think that's something I'll ever do.
