Hi,
what you do is currently the only way for citing math expressions in text fields. Some of the math stuff works in text fields (greek letters, logical operators), most, however, does not.
The text capabilities are just good for small comments. Report writing is painful, as you just have visual markup. Thus for heavy doc work (e.g. textbooks) better use full featured text processor and insert links to smath sheets where you want to go live. I do this with pdflatex, where the pdf result contains links to sm files. Most pdf viewers, however, inhibit calling progs from files. The only co-operative one I found so far is the pdf viewer in texworks.
Best regards, Martin Kraska
