I don't think so. Just look how the two variants of sqrt (\sqrt{a}{b} and \sqrt[a]{b}{c}) are handled and copy the relevant portions of code. If you think that you do not really understand how the different parts of mathed work together make Andre write some documentation :-) > Probably best to revert it. If you revert, then please remove all \unitfrac variants. Otherwise you create a regression, because \unitfrac[a]{b}{c} in 1.4 works fine as ERT, and it would not if you only kept the short variant.
