But there's something I still don't understand and is the meaning of that comma in there. As far as I know, the comma is a mark that delimits the addresses that acme understands, but I do not know how a comma is interpreted inside a regexp. I'd really appreciate if you could clarify this matter to me. 2009/6/26 yy : > 2009/6/26 hugo rivera : >> Hi, >> I am trying to select all c comments from within a file using acme, >> but I am unable to do it properly.
