I've always found this confusing. Can anyone point me to an explanation 
of the difference between  Super, Hyper, Compose, Meta, Alt, Alt_Gr, 
Mod1, Mod4?

My understanding so far is that "Meta" is another name for "Alt", and 
that Alt_Gr is for special characters, but that's the limit of my 
understanding. Google isn't much help either.

What are the other keys, what do they do, and where are they located (or 
what does one usually map them from)?

Thanks,

Richard
