A sun keyboard has a lot more interesting keys than your average PC keyboard.
Specifically, 'meta', "Open", "Front", "Copy", "Paste", "Cut".
[the 'meta' key is the little "diamond" key on a sun keyboard.]

But you can have these keys on your solaris x86 box as well!
All the magic is done through a command called "xmodmap". It tells your
computer to take the "raw" signal from any keyboard key, and pretend it is a
different key.

Please note that this is SPECIFIC TO Solaris! 
Or at least I presume so. I have notes on why, below.
But if you're not running solaris, you probably dont care anyways.
Unless you're runing OpenLook, in which case, you might want Copy and
Cut keys, too.

    ------------------------------------------------------------

First of all, xmodmap is normally used with an input file. All of the
commands below should go into a file like $HOME/.keymaps
Then you just have to run

  xmodmap .keymaps

once when you log in, and all your keyboard prefs will be set.

(or if you want this automated, You might try puttting the xmodmap command
  in $HOME/.dt/sessionetc, which you will probably need to create )

  ------------------------------------------------------------
To have a "kill-server" keysequence, first start Xsun with +kb.
Then bind a key to the keysym XK_Terminate_Server [0xFED5], with
 
  keycode XXX = Terminate_Server

Choose the keycode carefully. I havent figured out a way to have a
combination of keys like control-alt-del yet.

  ------------------------------------------------------------

If you have "windows" keys on your keyboard (The stupid M$ logo thing)
you can turn those into useful "Meta" keys. Well-written X programs allow
combinations of shift, control, Alt, AND Meta keys as modfiers.
For example, Emacs.

The commands to put in your .keymaps file will look like

  keycode 115 = Meta_L
  keycode 116 = Meta_R

Although a lot of times, Sun actually maps those "windows" keys to Meta
already now.

To find out the 'raw' keycode number of a key, you need to run the command
"/usr/openwin/demo/xev".

Then give that window keyboard focus, and press the key. It will then
show you the keycodes. You then need to look in 
/usr/openwin/include/X11/keysymdef.h

Mentally remove the leading "XK_" from all the names, and you then have the
normal names of keys.

EXCEPTION:
There are some "special" sun keys, that aren't in there. However, if
you look in /usr/dt/config/C/sys.dtwmrc, you will see special keys of
the format "SunXXXX"

So, to map  F9, F10, F11, F12, to
Front, Open, Copy, and Paste, you can use the following:
[remember, FIND THE REAL keycodes, this is just an example!!}

keycode 75 = SunFront
keycode 76 = SunOpen
keycode 95 = SunCopy
keycode 96 = SunPaste
[I personally never USE "SunCut", so I dont list it here.]

Except that the specific keycodes may vary depending on YOUR keyboard,
so you should use /usr/openwin/demo/xev to verify the keycodes on your
keys.

On my current keyboard, I actually use

! for F11-F12
keycode 129 = SunFront
keycode 130 = SunOpen

If you want to see the effects right away, you will have to use your mouse to
restart your window manager.

Additional important tips for XFree86:

To get your keyboard to work right under xfree86 4.0, you need to have the
following in /etc/X11/XF86Config, to override any existing XkbModel line:

Option "XkbModel"  "pc101_sol8x86"


Then, to stop Motif/netscape from complaining so much, you need to add the
following to /usr/dt/lib/bindings/xmbind.aliases
