Hi Hans:

This is asking Armin Varmaz' question in a different way, although I know even less. I would like to define a macro that is just an abbreviation.

For example, say I want to define a snippet \NPV which provides the text NPV$_0$, and NPV is in textfont while 0 is in mathfont. This should work everywhere---formulas, subscripts, footnotes, etc., and automatically appear in the correct sizing.

In LaTeX, this is easy to do:

\newcommand{\NPV}{\text{NPV\ensuremath{_0}}}

I can now use \NPV\ in formulas, footnotes, subscripts, titles, etc., and it is properly sized everywhere.

If you never need to use a full form of the abbreviation, then you can just use the same in ConTeXt. The equivalent of \ensuremath is \math; everything else is the same. \define\NPV{\text{NPV\math{_0}} I would, however, write this slightly differently (even in LaTeX) as \math{\text{NPV}_0} but that is just a stylistic issue.

Is there a recommended way to do this on conTeXt?

The usual way of defining abbreviations in ConTeXt is \abbreviation [NPV] {\math{\text{NPV}_0}} {full form} Then you can use \NPV\ for a short form of the abbreviation and \infull{NPV} for the full form. The advantage is that you can also get a list of used abbreviations. Aditya
