I would like, of course, to be sure the keybinds are right. However, having just tried globalff.el, I am truly grateful to the programmers who did this. Very useful. I cannot find an email address to send a personal thank you note.
I will probably try locate.el. Globalff is fantastic, but it is not as easy as it could be to manipulate the files one has located. At least for me, yet.
Thanks for the opportunity to express myself about this fantastic piece of work.
