Absolutely! I didn't know of apply.
I realized a major problem with the interface is that a lot of
commands act differently depending on if there is a region or
not. An example is replace-string. With the function in the OP,
the region is ignored! Very confusing, as intuitively, once set,
you expect it to delimit the search-and-replace.
I worked around that with an, eh, interface to replace-string.
But that's getting tedious if it has to be done for a lot of
functions...
(defun rs (from to)
(interactive)
(let*((scope (if mark-active
(list (region-beginning) (region-end))
(list (point-min) (point-max)) ))
(start (car scope))
(end (nth 1 scope)) )
(save-excursion
(replace-string from to t start end) )))
