I see. Explanation accepted. So what you're saying is that we actually should have buttons for both \mathsf and \textsf within math (no matter how implemented)? Anyway, I suggest you do something that fixes the 'haywire' behaviour with a minimum of collateral damage. Add textsf to symbols for all I care :-) Martin
