Generally, these problems seem due to a broken font system (at least
according to the answers Joris have be giving on the mailing lists for
similar problems). I cannot say more, but your additional message
seems to point in that direction too.

I suggest you make a clean intallation of teTeX.

I understand your are frustrated, but it would be more helpful if you
give a clearer description of your problem: a procedure to describe
the problem with the output of xmodmap at the key points and how the
observed behaviour is different from the expected behaviour.

Actually, TeXmacs uses xmodmap to remap keys to modifiers. Internally
it only maps ModN to a given symbolic modifier (A, M, H etc.). Also
there is some confusion with the AltGr key because it should not
switch key-plane when used as Alt modifier. TeXmacs does its best
handling the mess of Xlib keyboards events, but that is not yet
optimal.

On my iBook, my ~/.xsession files does:

xmodmap $HOME/meta.mod
startkde || xterm

And $HOME/meta.mod contains:

keycode 64 = Alt_L
keycode 115 = Meta_L
clear mod2
clear mod4
add mod2 = Alt_L
add mod4 = Meta_L

In short, that maps the "alt" key to mod2 (which is standard for Alt)
and the "apple" key to mod4 (which is standard for Meta).

If I remember well, by default the Alt key is mapped to Mode_Switch
(at least that is that way on XDarwin). So I also use another file
$HOME/alt-gr.mod to get my alt-gr key back:

remove mod3 = Mode_switch
keysym KP_Enter = Mode_switch
add mod3 = Mode_switch

That remaps AltGr to the iBook keypad-enter key (which I do not use).

Hope this helps.
