Re: Whats this GUI thingy?
"I have three Emacs sessions"
But if you use the GUI version you only need 1 session with C-x 5 2 (make-frame).
As for a mouse with Emacs, I do like/love using nothing but a few mouse clicks to cut and paste a block of code, to non believers it looks like Jimi Hendrix playing his guitar with his teeth.
