mapping the keyboard under GNOME 2.6

[Shot <shot@hot.pl>]

Hello.

I'm using GNOME 2.6 with the Polish keyboard layout, but I'd like to
be able to input some custom characters easily (curly quotes, em and
en dashes, ellipsis, some German characters, etc.).

I've read the standard way to do it is through xmodmap/xkeycaps, but
then I've also read it's not working in GNOME 2.6/Metacity (at least
not the way it does in other DEs/WMs). Is this the right path to follow?
If so, what's the solution to have xmodmap working in GNOME 2.6?

I also remember reading something about the compose key, and, fair
enough, I can assign the compose key to Caps Lock, and it works (i.e.
I can get the ae ligature). Is there a list of all characters one can
generate this way (and how to generate them)? Can I somehow define my
own combinations (e.g. for curly quotes)?

Cheers,
