Possible to redefine function keys via Ansi ESC sequences in terminal?

Question

If it is possible, I would be be very grateful if somebody could be so kind as to show me a couple of examples.
BACKGROUND:
I want to reconfigure my function keys in terminal,via ansi-escape-sequencenses from
a script, before invoking the "screen" utility, to make it less cumbersome to use.
It's really nifty, if you want to see som manpages, without ending up with a zillion of terminalwinwindows, and you can name the windows too, so you can easily see the difference between
terminfo and bash for instance, - but the keypresses for invoking screen is quite cumbersome.
I will try do it by ansi-sequences, but I haven't managed to do that yet.
I want to store other keypresses, like [^A"] on functionkey F2 for instance.
I have no intention to restore the keys, as i just close the window when I'm finished using screen.
I have configured my function keys in terminal, and I think that writing new values for them in the defaults database, and be able to use the new configuration from within terminal is a little to much to expect.
If anybody has a solution not including ansi sequences, I'm open for that as well.
Sincerely

Thank you. That wasn't what I had in mind, but thats what I'll go for, as I can't seem to figure out how to send and ansi escape sequence that does it, and creating a new terminfo file with the new settings, exporting it, and and creating a new subshell is just too much work. "Screen" runs fine now, with some function-key bindings.
