John,

The manual "Using the X Window System on Apollo Workstations" is the place to
look for some of this -- it's a good summary, but not an exhaustive treatise
on X. The answer to your question is that you will need to use the client
"xmodmap" in order to simulate the keys which are not physically present on
the Apollo keyboard (PF1-PF4 as an example).

Since you are running in a "dm owns root" configuration, you'll need to take
into account the "keyboard.config" file which tells XApollo "this list of keys
doesn't exist for X, pass them through to the Apollo Display Manager". This is
important because you don't want to remap keys for xterm which XApollo will not
GIVE to xterm. See section 2.2.2 in the manual for a detailed discussion about
the /usr/lib/X11/keyboard/keyboard.config file.

Once you have picked a set of physical keys to emulate the PF keys, feed this
to xmodmap using the physical keycode and the keysym name (from the include
file /usr/include/X11/keysymdef.h).

Example - you want to make the "AGAIN" key map to PF1. Looking at the output
of "xmodmap -pk" you see that it is labeled "Redo" (which agrees with the entry
in the keyboard.config file), and it is keycode value 158. Looking at the
include file keysymdef.h, you see "#define XK_KP_F1 0xFF91" which is the entry
for "keypad function key 1" - also known as PF1. The xmodmap client will take
either a file entry or a command line remapping, so you could invoke it as
< xmodmap -e "keycode 158 = KP_F1" > (the quotes are required on the command
line) and the deed is done.

If you don't have a copy of the manual, you can get one by using the order
number "015213-A02". Hope that helps.
