Multi-letter variables in math mode

Multi-letter variables in math mode

[Thaddäus Töppen]

Hi.

Sometimes I use variables (really rather abbreviations) in math formulas.
It seems to me that the letterspacing is a bit too wide then.
Maybe math mode thinks I want to multiply the letters as if they were variables for themselves.
Is there a way to preserve normal letterspacing locally in a formula?

Kind regards.

Latex provides a \mathit macro for such variables. From what I understand, 
this is essentially the same as using \text{\it ...}. For example:

\starttext
\startformula \startalign
   \NC efat \NR
   \NC \text{\it efat} \NR
\stopalign \stopformula
\stoptext


You could wrap this around in a macro, if you wish (but don't use \mathit, 
as that is reserved for normal math in context).
