[vox-tech] missing vim

Already been through that, but thanks. (-:

Note quite. Suppose my cursor is in the "l" in "looking" in the above
sentence, and I want to move it to the "d" in "downarrow". If they are
two physical lines, that is easy, but if it's just one long line that's
been wrapped, how do I move up by virtual/screen lines instead of
physical lines?

In vim, I could type gk to do the above.

I don't have any problems going to specific lines; seeing line numbers
on each line is just an interface tweak I'd like to be able to make.

Didn't know that one! It's handy. Thanks.

H/M/L basically saves time when I see text I want to edit at the top or
bottom of the screen but my cursor is many lines away.

Sure. 

def printstuff():
	print "some stuff"
	print "some other stuff"

becomes

def printstuff():
----(2 lines)--------------

so the function is essentially collapsed until I inspect it. If your
source code contains a lot of functions, folding lets you see an
overview of the structure of the file without seeing the contents 
of each function.

When you expand a function, you see an overview of its logic without
having to see all the nested stuff, etc. Very nice. Load a reasonably
large C/C++ source code file in vim, type ":set fdm=indent" and play
with it. (-:

One other question, and I can't believe I forgot this one.

Are there emacs commands for moving forward or backwards to a specific
character? I use f/F and t/T (and ;) all the time in vim and it saves me
from spending a lot of time holding down arrow keys.
