    They're all different. xterm uses the X toolkit resource mechanism.
    ("man X" and "man xterm" tell all of the details). aterm recognizes
    a small subset of that. gnome-terminal - menus (though occasionally
    someone comments that there are files that can be edited).

    like this -
                       Shift <KeyPress> Prior:scroll-back(1,halfpage) \n\
                        Shift <KeyPress> Next:scroll-forw(1,halfpage) \n\
                      Shift <KeyPress> Select:select-cursor-start() \
                                                     select-cursor-end(PRIMARY, CUT_BUFFER0) \n\

    You can specify stuff like that, but it gets tedious to setup.

    The real question is what the application expects. Most aren't hardcoded,
    but expect to match some terminfo entry.

    It's a resource value. You could for example specify it on the command
    line

            xterm -xrm '*oldXtermFKeys:true'

    but usually it's in a resource file. The system app-defaults (resource) file

            /usr/X11R6/lib/X11/app-defaults/XTerm

    is customizable. But you can set $XAPPLRESDIR to point to your own
    directory and use similar resource files there (however, a lot of systems
    mis-use xrdb to load all of the resource files, making them essentially
    static rather than dynamic).
