help: reach the cheatsheet with H as well as F1

F1 is swallowed before it ever reaches us on at least one setup here -- the
app's own binding fires when the key is injected directly, zellij has no F1
binding of its own, and every common F1 encoding written straight into the pane
(SS3 ESC O P, CSI ESC [11~, CSI-u ESC [1;1P) opens it. So the key is being eaten
by something upstream, which is not ours to fix, and a cheatsheet reachable only
through a function key is fragile anyway: terminals and multiplexers claim them
routinely.

H opens and closes it too. '?' stays with the incremental search, which is what
it has always done in the code views.
