[Wylug-help] Compose key sequences

[Chris Davies MBCS]

I've got a compose key defined as Right-ALT, and it works wonderfully. I can 
enter all sorts of wild and wacky characters, with key sequences such as 
Right-ALT !! (which results in a Spanish "start exclamation" character, 
otherwise known as an upsidedown exclamation mark)

I would really like to add three additional characters to the mappings: "is in 
the set of" (merged "C" and "="), "is not in the set of" (merged "C" "=" and 
"/"), and "is not equal to" (merged "=" and "/").

Any suggestions how I can add these compose sequences, or otherwise get the 
characters available? Using Gnome if that's important.

Cheers,
Chris
