	To change the function key bindings in mgx:

	The actual function key bindings are in the file "ttykbd.c", in the
function "ttykeymapinit". All other keys are bound in the "key" array in
the file "symbol.c". If the function you are binding to has already been
mapped (in the "key" array definition), then you only need to use the
function "keydup( KEY fkey, char *function_name)".  If you are adding a
function that has NOT been previously defined in the "key" array, you
must use the function "keyadd( KEY fkey, int (*func)(), char
*function_name)". Things bomb spectacularly if you mess up here! 

	The "help" line for function key usage is done using the functions
"modeline" and "rotatmode" in the file "display.c", which is not really
the correct place for a user-accessible function, but I didn't want to
make another global variable, and rebuild the whole program again!. The
help usage attempts to model after the ACCELL function key help, and
should be updated when the function key bindings are changed.
