You can do that in TM as well. But it folds full lines.
Ah, there it was. However, when I hit F1 on the keyboard the automation menu gets slightly highlighted (as though something in it was activated) and then my text disappears without leaving a folder marker behind. I can get my text back with an edit->undo.
Also, while on folding, is there some way to unfold all foldings? And remove the folding markers the view->fold current block leaves behind when you unfold it again?
