Thanks for this - looks quite useful! Just downloaded and was about to explore a regex I am working on.
[+*]\d+
gives the notice "Unknown token FAKE-ENTRY in parse tree"
The target string is "+100929 asd;askjd;;"
BTW, various emacs key bindings don't work - arrows, control-[bfpn] and copy and paste are not available.
Thanks again, Alan
