And for playback cursor, even less idea how it works? Ok, I see. Part of the problem is terminology. Region is the name of a type of object on a track. You want to delete a range of audio from a track, which isn't necessarily already defined by a region. Even the word 'delete' is tricky, because I assume you don't want everything after the edit to be moved forward in time. As to the deal with the edit and playback cursors... This goes waaaay back... In the world of text-editing it is customary to have at least three 'points'. p1 and p2 defining a range, region, span, whatever you want to call it. These are the 'edit cursors'. And c, being the blinking cursor where inserted characters go. Different edtiors use different terminology for these, but the concept is the same and, usually, the available operations are equivalent. This 3-point editing extends fairly well to non-linear audio editors. (some edtiors have 4-point editing which is even harder to explain). In a text editor, it is indeed common to have functionality to "delete the text between p1 and p2". I've never seen one that had a function to "blank the text between p1 and p2" though, and that's where the analogy breaks down a bit. Now that the history lesson is over and you can see what the idea was, I will freely admit that the array of available editing operations is not as fleshed out as it could be. This is due less to them being complicated to implement than to it being hard to come up with good key/mouse bindings to assign to them. FWIW, non-timeline has more editing ops that a lot of NLEs do. And in most you have to switch to a different tool to e.g. split regions and then back to the selection tool to move or delete them or whatever. Since non-timeline is modeless, splitting a region twice (to chop out the part you want to delete) and then deleting the middle is actually just as quick and easy to do as it would be to define an edit range and invoke the key combo to delete the range. Which I suppose answers the question of why, even though I often perform the same operation, I've never bothered to add an explicit function to do it.
