No, I just mean I don't understand how to use it and can't find any
usage notes. What's supposed to happen- does Synedit call the
OnReplaceText handler and expect this to actually do the search/replace?
Or is the handler there to allow a confirmation dialogue to be
displayed, after which code like you've shown above should be called
explicitly?
(I think I understand the regex usage in your example, thanks for that).
