I'm trying to highlight all the name of (a particular class of) subfunction who all reside in a subform\...\...\...\ folder, so they actually have a quite long name.
I used the "subform" prefix, and it worked fine, but only for short names.

"SubForm\wizards\create_new_app" gets highlited, but "SubForm\wizards\create_new_application" does not (even worse, it IS highlighted until you type the "l" in).

I think it's a bug, or at least a limitation which is not clearly stated anywhere.
