Can you explain this a little better. Never heard of Fold view so not sure what you actually mean. Explain a situation in more detail i.e. what would you like to be able to do in the midi editor.

''Fold'' view only shows the active notes on your piano roll. For example, if you have midi notes on C4 and B4 and hit ''fold'', the piano editor will only show the keyboard range from C4 to B4 with its corresponding notes.

SHIFT-E and SHIFT-W will zoom in/out vertically, with multiple key presses. I don't see a single button or key stroke to automatically zoom to the full range of notes used.

In Drum mode, the part editor can be set to Hide Unused. This might get you what you want combine with vertical zooming if you're editing drums/percussion. Not very useful for keys ...

I know this is old Post but only post I found on subject that did not answer the question. The answer is this is done by a keyboard shortcut. Go to keyboard shortcuts, search for hide, assign a key to hide unused, hit apply and you are done
