So they're finally shipping Type 4's on desktop Sun-3s (and presumably
Sun-4s, as well), as well as deskside 3's and 4's, and '386i's....

>Does anyone know the keysym story for these?

The diamond keys are, as you note, the same as Left and Right on Type
3's.  As such, they should have the same keysyms (left-hand and
right-hand "meta", I think).  (Heck, as I remember they should have the
same *keycodes*; the Type 4 keystation numbers are mostly like those on
the Type 3.)

>I really want to turn compose and alt graph into useful citizens.

Good luck.  To make them useful for what they're intended requires some
rewhacking of XLookupString, at the very least.  Alt Graph is intended
to let you get at the third symbol on some keys on non-US layouts;
unfortunately, I don't think XLookupString is prepared yet to
acknowledge the existence of keys with three symbols on them (i.e., to
fully support keycode-to-keysym mappings with more than two columns).

Compose is intended to introduce a two-key sequence that gets mapped
into some e.g. ISO Latin #1 character (for instance, Compose+r+o maps
into the "registered trademark" symbol).  I'm told DEC was looking at
some scheme for supporting this in X11.

I think there is a keysym hiding somewhere that corresponds to
"compose".  I seem to remember there being none for "alt graph"; there
should be one.  I don't think Sun is the only one with "alt graph" on
its keyboards.
