                    Linux 1.1.59 Twelve Consoles Example

The result of the following is that tty[1-8,12] are, respectively, activated by
<left-alt>F[1-8,12].  I wanted F12 for root and/or something running "top -s"
while F[1-8] run whatever and can simply be extended through F11 without moving
the F12 functions.  It seems to be working fine.  I have had all 12 of them
logged in at once in testing.
