My, you seem to have a lot of questions. Fortunately for you, they all
seem moderatly interesting/hard to find and I have some free time, so I'll
do my best to answer them. (I'm sure you did your googling and
documentation-reading anyway, right? (Actually, I can see that you've
definitely been reading documentation.))

Screen has a command line, of sorts. Just type
and then you can enter any screen command, including 'bindkey -d'. If you
wanted to bind it to a key (which is probably silly; 'C-a ?' should be
sufficient for everyday use) you could use, say, the command
bindkey -k k1 bindkey -d

As the manpage says, -k uses termcap keynames. It so happens that, for
historical reasons, termcap uses k? for 1-10 and F? for 11-63. (Yes, 63.
It goes F1-F9,FA-FZ,Fa-Fr.) termcap has grown up over a long period of
time and is now rather crufty, but it is a standard that a lot of people
know, so it's not unreasonable for screen to use its key definitions.

Hm. I don't see a way to do this with the termcap codes, since I don't
see one for Ctrl-PgUp. The hackish approach is to do something like
'cat > /dev/null' then press C-v and the key conbination to see what
characters your terminal sends for that key. (My gnome-terminal seems to
send ^[[5;5~ for C-PgUp and ^[[6;5~ for C-PgDn.) Then you just use
bindkey to capture that key sequence:
bindkey ^[[5;5~ previous

There are termcap codes for this. 'man 5 termcap' tells me that they are
kh for Home and @7 for End.
> Typing CTRL-a a gets a little tedious.
Indeed. This is why many people rebind the escape key to something they
use less often. I have mine set to C-z.
