Yes, we should make it easy to get the arrow key bindings.
It should be easy to have either behaviour, whatever the default is.
We should be aiming for a situation where the interested user only
needs to add a single command, either "create_arrow_key_bindings" or
"remove_arrow_key_bindings", in their .zshrc -- the command should be
a zsh function in the distribution.

Easier, but putting in heuristics such that arrow key sequences from
terminfo may or may not be bound makes it more difficult.  If arrow keys
are bound by default, then the shell code to turn them off is going to
have to exactly duplicate the logic of the C code that turns them on.
Btw, what happens to these bindings if $TERM gets changed?

This difficulty with turning off the bindings is why I suggest that the
bindings should be off by default -- it's easier to have only one copy
of the logic, in some shell code that creates the bindings.

It looks useful.  Misc makes some kind of sense, but I'd put it under
