Considering I'm running kde-4.6.5 here on pclos, I just tested mine and a 
plain ctl+f does indeed bring up the find bar.  So this might be a distro 
specific thing.  But I'll also submit that the use of "genius" was 
obviously satirical. ;p)  Whomever did that is I trust suitably chastised 
by now.  Ditto for grabbing mc's f-keys.  Inexcusable, and should be the 
subject of a session with a LART out behind the barn IMO. IIRC those have 
come back, but don't recall which update did it now.

Cheers, Gene
