How would I apply the last keyboard macro to each line that begins in the region which match a certain regular expression. For example, say I was editing a Perl script and wanted to apply the last macro to all line which consist solely of a comment. For example:

Bind the macro, e.g. with C-x C-k b 1 , and create another new macro
that does the searching part and then calls macro-1.
Or edit your macro (C-x C-k e) and prepend some searching `code'.
