As far as keystrokes go, terminfo isn't a settings database that
terminal emulators use to decide what escape sequences to send when you
press certain keys; it's a translation table that applications use to
convert escape sequences back into keystrokes.  If you want your
emulator to emit something other than Esc [ A when you press F1, you'll
have to edit its source (or if you're lucky, it can be configured with
a config file or X resources).  Changing terminfo away from what your
emulator emits will only confuse your application.
