mailing-list for TeXmacs Users

[Ken Feyl <address@hidden>]

Dear David, you are the man for giving me such a detailed reply. Your 
suggestion regarding the font problem, however, did not fix my weird 
behavior, even after I re-installed tetex and texmacs several times. 
Ultimately, I discovered from the Console, the problem roots to TeXmacs' 
failure to find the font cmsy10. Then, a friendly suggestion from a fellow 
user suggested that my ~/.TeXmacs directory may be the source of the problem. 
And whaddya know? Nothing, nothing at all in the ~/.TeXmacs/fonts directory. 
Just an empty directory structure. Quite suspicious. So, again on my 
comrade's suggestion, I renamed my whole .TeXmacs directory, to .foolish, 
rebooted TeXmacs and presto! When I tested a subscripted infinity this time, 
it unpacked some font package and gave me an infinity.

This was rather weird. But, in summary: if you get this problem, wipe out 
your ~/.TeXmacs directory.

More news soon on the Alt-Meta situation. I will try your suggestions. BTW, 
to explain it a little more clearly, I did have my own .xmodmap with the 
aforementioned modifications, and they show when I launch OroborOSX, get an 
xterm and run xev. However, when I underwent the below procedure, it would 
forget my settings on every launch.

1) Boot TeXmacs
2) Hit $ to go into formula mode and then alt-f. Just the letter f.
3) Select Preferences-Keyboard-Alt-map to A modifier.
4) Hit alt-f. A fraction.
5) Quit TeXmacs and reboot.
6) Step 2 again. Still the letter f. Every time I run TeXmacs, I need to 
repeat step 3.

But I will try some of your alternative suggestions now, and let you know how 
it goes. But this is hopefully a more precise explanation of the observed 
behavior.
