You need to compile MG 2a with XKEYS defined.  After that, MG will
look for a file called .mg-TERM, where TERM is the value of the
logical name TERM (e.g. .mg-vt100 for a vt100 terminal type). If
found, it will read and evaluate that file just like .mg.  This allows
you to have different function key setups for different terminals,
albeit in a slightly different manner than GNU Emacs does.

I've included an example .mg-vt100 below, which defines the arrow keys
in VT100 application mode.  For more information, look in
[.SYS.DEFAULT]README, which also explains the termcap terminal driver.
