You think about something like:

Replace this:   ^([a-zA-Z]+)([1-9][0-9]*)
With this:      \2\1


Unfortunately it is not possible yet... I'll add this to our TODO list,
but it won't get into gcmd before 1.2.5

But... there is a workaround for your problem:

     1. file extension is accessible in template as $e
     2. If you know the number of digits in advance, you can use
        python-like ranges in templates, e.g. $n(0:-1) will bring you
        all characters till the last one in the filename.

So in your example use template (but not regex!!!):


to get 4foo.bar

Hope it'll help,
