Here is a suggestion:

* I select some lines of text with Shift+Arrow key.

* I then press M-[ to visually replace the selected (complete) lines by a
   single line which may for instance look something like
 	====> (folded lines 237 to 274) <====

* To unfold the lines, I place the cursor on the line above and press M-[.

(As an aside: why doesn't Shift+PageUp/Down select lines too (Nano 7.2)?)
