Bg:  X.V11R4, patch level 18, patched to handle Compose characters and
"dead" keys.  Compiled on a sun4, type 3 keyboard, os 4.1.


			Bug #1:

        I'm trying to define keys to have more than 2 symbols each
with xmodmap, for ex:

keysym semicolon = eacute colon semicolon Eacute

   In order to have a ;, I have to have a "Mode_switch" key, no problem
I defined Meta_L to be it:

clear mod1
keysym Meta_L = Mode_switch
clear mod3
add mod3 = Mode_switch

   I used mod3 rather than mod1, because for some programs like xterm
the mod1 (Meta) is special: it turns on the 8th bit, which is not what
I want.  In order for the Mode_switch key to work, it has to be a
modifier.  Fine so far: it works.

   Now I want to have the Meta_R key to have the same effect so:
keysym Meta_R = Mode_switch

   Both keys should be generating the same things, but they don't!
the left key is considered to be a modifier, but not Meta_R.  No amount
of clear mod3 and add mod3 = Mode_switch seem to work.

   In my humble opinion, this should work: both keys generate the
same keysym which is modifier, but in one case it is and in another case
it isn't.  Any solutions?

   A few hours later, a new twist:
keysym Mode_switch = Meta_R
clear mod3
add mod3 = Meta_R Mode_switch

   and now they both work as a mode_switch key.


			BUG  #2

   I tried to define the "Linefeed" key to be a caps lock:
clear lock
add lock = Linefeed

   Linefeed has no impact as a cap lock key BUT it does
seem to affect the binding of the keys of tvtwm!  Meaning
press linefeed once (you get a linefeed) and the binding of the
keys of tvtwm no longer work: different modifiers.  No impact on
character generation.  Press linefeed again (no linefeed generated)
and the key bindings of tvtwm now work (still no impact on character
generation)!
   This is 100% reproducible.
