Salix OS

How do I set up a compose key so I can have an alternate keymap?

What I'm trying to do is set it up so that each key outputs the appropriate symbol from the International Phonetic Alphabet when I'm holding the compose key. Ideally, I'd like to have a couple different compose keys to access several variations of IPA characters. From what I've been able to find online, this involves tweaking the xmodmap file. But the online tutorials have all been for other distros. Given how much variation there is between distros I can't really rely on that information. So I'm hoping somebody here can guide me to the answer.

The tutorials you've found should apply just the same for salix. If you care to link to one of them we could tell you if there should be anything different.

I'll track down a couple of them when I get home tomorrow. It looks like just a matter of tweaking a couple X11 files to define the keymap and set the chooser key. But I really want to make sure before I start messing with it.
