Hi ConText friends, I am trying to increase the vertical distance between the underbrace and the part of the equation above the underbrace. \startformula \underbrace{x+y+z}_{\blank[1cm]\mathrm{my text here}} \stopformula I've tried using \blank and \vspace, but to no avail. For example: \underbrace{x+y+z}_{\blank[1cm]\mathrm{my text here}} ...does not work. The documentation on underbrace (and overbrace, underbracket, etc...) in the ContextGarden wiki seems to be very limited, and I was not able to find any user-supplied arguments for increasing this vertical distance. There are various solutions available for LaTex, and they require external packages (e.g., BigStrut, vphantom) that redefine the strut height. I hope I'm missing something simple... Any help would be greatly appreciated! DY Hung
