Indeed. I didn't even realize that we had made such a silly change. It was bad
enough to waste `home' on `beginning-of-buffer' (prior to Emacs 21, when that
silly change was made).
Now if `home' were bound to something like the following, which is repeatable,
then it would be a lot more useful. First time: bol, subsequently:
next/previous line's bol.
I use this and the eol version _all_ the time (but I use them on `C-a' and
`C-e', not `home' and `end').
(defun beginning-of-line+ (&optional n)
"Move cursor to beginning of current line or next line if repeated.
This is the similar to `beginning-of-line', but:
1. With arg N, the direction is the opposite: this command moves
backward, not forward, N lines.
2. If called interactively with no prefix arg:
If the previous command was also `beginning-of-line+', then move
to the beginning of the previous line. Else, move to the
beginning of the current line.
Otherwise, move to the beginning of the Nth previous line (Nth next
line if N<0). Command `beginning-of-line', by contrast, moves to
the beginning of the (N-1)th next line."
(interactive
(list (if current-prefix-arg (prefix-numeric-value current-prefix-arg) 0)))
(unless n (setq n 0)) ; non-interactive with no arg
(if (and (eq this-command last-command) (not current-prefix-arg))
(forward-line -1)
(forward-line (- n))))
