It's a damn fine coding editor one you get the hang of it. The flow fo
the key strokes is pretty good. In VI land I always felt crippled by the
distant escape key, my hands aren't so big. The control characters do
the majority of the editing and you really only need to use escape
periodically. Of course others feel much more comfortable with VI, I'm
not trying to start a war.

I don't like that way of thinking about it. The way I view it,
everything is a little lisp function and some of them are bound to keys.
When you run out of keys or forget them you esc-x to the lisp interpreter
and run the function by name. You can also write lots of your own lisp
functions. I'm partial to the cgvg code navigator so I consed up a
little lisp function to call it from within emacs. Some people like the
do all their function and class prologs the same way and they can write
little lisp functions to do it for them.

Emacs also has a wicked help facility. For it's complexity it is
remarkably well documented and once you learn a few keys and some
nomenclature it is easy to learn the rest with the help facility.
