Shortcut to have the cursor move X nu,ber of lines up or down

Shortcut to have the cursor move X nu,ber of lines up or down

[Rami A]

I would like to have the cursor move up or down X number of lines.
Kind of like C-n and C-p but instead of 1 line to be a programmable X number of lines.

Thanks in advance.

`C-h k C-n' tells you that it runs the command `next-line', and that a prefix
arg does what you want: e.g., `C-6 C-n' moves down 6 lines.

If you want a command that always moves a particular number of lines then roll
that argument into the definition.

(defun six-lines-down ()
  "..."
  (interactive)
  (next-line 6))

Wouldn't that be: 'C-u 6 C-n'? You can do 'C-u 6 C-p' to go up,
or 'C-u -6 C-n' to go up.

C-6 has the same effect as C-u 6.
C-- 6 has the same effect as C-u -6.
C-- has the same effect as C-u -1.

That depends upon whether you are running emacs in a graphics window
or in a terminal window.  If in a graphics window then emacs can tell
that you are pressing Control + 6 individually.  But in a terminal
window then Control+6 produces C-^ instead and sends that to emacs.
And the rest produce a variety of other results.  Control+2 produces
C-@.  Control+3 produces ESC.  And so forth for the rest.

True.  A useful correction for those using `emacs -nw'.  Thx, Bob.
