(You don't need the `C-x C-x' here, unless you want to
see highlighted what `C-w' will delete.)

OK, but what you show above does not work, in general,
for regexps.  Regexp search forward and backward do not
find the same text, generally.

If you regexp-search for the same text, `one-two,
buckle my shoe', no problem.  But if you use `o.*oe'
you'll be in trouble.
