Hi Richard,

( and ) group alternatives in addition to capturing. You want to group
your alternatives after the prefix (^%) which you always want to match
(at least I think you always want to match that). Otherwise the prefix
^% will only be part of the first alternative. If you capture as a
side effect that is OK.

You could also use:

  "^%system\\|^%junk\\|^%spam"

if you *really* don’t want to capture. :)

best, Erik
