Migrating from Jove - help?

[Alan Ezust]

Using:GNU Emacs 21.3.1

I've been using jonathan's own version of emacs since 1988,
and I've tried gnu-emacs a few times but keep giving up because
I can't figure out how to do jove-like things in it yet.


1. If I make changes and want to exit without saving, in jove I do
ctrl-x ctrl-c
it asks: "modified buffers exist - exit anyway?", 
I say: "y<return>" and it lets me out.

But with emacs, it asks me first this other question, which requires the
opposite yes/no answer, which always screws me up:
"save file? y/n" 

And then, if I say N, emacs asks me ANOTHER
question, and it won't accept a simple y/n, so I have to type
"yes<return>"

Can I have it skip that first question, and also permit me a single letter 
response for the second?

2. What is the command to toggle line-wrap in the current buffer?
   I did an "apropos wrap" and found no commands that actually toggle 
line-wrap.

3. How do I toggle the display of line numbers? 
  I did an "apropos number", found a command called
   "line-number-mode" but it seems not to do anything. Why is that?

I can answer the easy ones.

M-x autofill RETURN

M-x line-number-mode RETURN

Each time you execute the above you'll see an "L xx" (where xx is the 
line number) (dis)appear from the bar above the minibuffer.  I guess you 
have to know where to look to see it.

No and no.  But you can shoot yourself in the foot like this:

(global-set-key "\C-x\C-c" 'kill-emacs)	; was save-buffer-kill-emacs

Isn't the answer to the second question yes?
(fset 'yes-or-no-p 'y-or-n-p) in your ~/.emacs ought to let you just
answer with a y instead of a yes or no.
