backward-symbol

backward-symbol

[Andreas Roehler]

As `forward-syntax' and `forward-symbol' exist already,
these two functions--following scheme of backward-word
in simple.el--could be helpful.

Propose to integrate them into thingatpt.el


(defun backward-symbol (&optional arg)
  "Move backward until encountering the beginning of a symbol.
With argument, do this that many times."
  (interactive "p")
  (forward-symbol (- (or arg 1))))

(defun backward-same-syntax (&optional arg)
  "Move backward until encountering the beginning of a same-syntax.
With argument, do this that many times."
  (interactive "p")
  (forward-same-syntax (- (or arg 1))))

Thanks

I don't see a need to make a "backward-" version of every motion
function.  It is not hard to pass -1 as an argument.

It's not?  How do you do it?

`C-u -1 ...' or `ESC -1 ...' or `M-- M-1 ...'

... and note that you don't need to actually type "-1" after ESC or C-u,
you can just type the "-", e.g. "ESC -" or "C-u -", or with a meta key "M--".
