Re: How to put a circle on top of a character

Hi Hans,

Regarding what you have added on line 1327 of math-stc.mkvi, that line should be

	\definemathover[\v!symbol][interiorset]["2218]

(instead of "2217).

I added also a wiki page for mathstackers:

	http://wiki.contextgarden.net/mathstackers

Best regards: OK
