Here’s a bizarre problem: All of a sudden I couldn’t hit the Ctrl F2 keyboard shortcut to set focus to the menu bar. It wasn’t because the shortcut was disabled through Ctrl F1 (by default the functions for keys F2 to F6 are disabled by default), it was due to some bizarre problem with Quicksilver – keyboard navigation voodoo. For some reason ^ F2 would only work after I had Command Tab’d to Quicksilver, hit Ctrl F2 (which worked, focus was set to the menu bar), afterwards, the shortcut worked as normal with all other open applications.
Quicksilver is the bomb, btw, in case you didn’t know. Dock? What Dock?
