How do I add my own functions to the nonitalic list like sin, ln etc? I want eg. Col(A) and span{...} to not be in italic automatically.

I've seen in the typesetting rules, and tried adding them to dependency suppresion, but that doesn't accomplish anything :p

And #2: When I write {....}, I always get "Error, unable to match delimiters" on the last "}" -- how do I remove that message?

Thanks!

Hello

When I export maple files into html files (with gif images), I often get jibberish text after "a>b". Maybe it's rendered as a html tag or something, I don't know.
