[Gprename-users] capture group

[Gabor P. <and...@gm...>]

Hi,
Very nice program, I use it a lot.
Here is my question: is it possible to I capture groups?
Something like:
AAA_bbb   -> bbb_AAA
/  (.*) _ (.*) /  $2 $1 /        # extra spaces added for readability

Even if I check regexes I the replacement interpreted literally.
(I guess special characters are escaped during runtime).

Any ideas?
