I still have the keyboard shortcut to the Quick Entry (F13), but the Clipping trick (F14) is lost and there's no way to make OF re-register that one. Tried multiple things (uninstall/install the Mail Clip-o-tron), checking shortcuts in Sys Prefs...

I've tried other keystroke combinations - to no avail.

EDIT: I'd suggest that everyone also does a restart after following the guidelines in the sticky. That solved my problems: a complete system restart.

All systems functioning properly now.
