The emulator may or may not decide to handle those keys itself; that's
down to the way it's set up. Most terminals *should* be able to do
this. If it doesn't, then the shell can use those keys instead.
So it depends what behaviour you're expecting. If you want to be able
to scroll back screenfuls to see what's there, then this is entirely the
terminal emulator's business and nothing to do with the shell at all.
If you want the terminal emulator to leave the keys alone so that you
can bind them to some function in the shell, then you need to configure
the terminal emulator to do that, and you will be able to bind them in
the shell by the usual tricks (e.g. type "read" and see what turns up
when you hit the key).
However, the first thing to do is establish whether what you're trying
to do is a terminal function or a shell function. The most obvious use,
scrollback, is a terminal function.
