I wrote a command that sends the cursor to another buffer window, and
lets you do whatever you want in that window, until you hit "q" (this is
a special-mode buffer so insertion isn't an issue), whereupon it pops
you back to the original window. It uses a transient keymap to do that,
which is yet another approach you could consider.
