If I highlight some code (just a few lines), and then use Source, Format (Ctrl+Shift+F), the entire file gets reformatted. I'd rather only the selection was passed to perltidy. Is that possible?
Possible yes, implemented no. You should add it to the RFE tracker.
Sorry to resurrect this thread, but I see no progress on this item. Currently lack of this functionality is stopping me from using the format function. Any chance this might be added soonish/at all?
