Herbert, while we are at it, does it ever make sense to use \textrm
in
math? I am a bit puzzled about what this really does. I would tend to
use \mathrm{} for a variable name in upright shape, and \mbox{} or
\text{} for something which is more like a word.
I believe the advantage will be for entering more than one word, with
spaces
and all. At any rate, the simple toggle to insert text this way
means that
that is what I have been doing for years with it, to no ill effect.
this is what I wanted to say, if you know what you are
doing, \textrm is a nice macro inside math ...
I find \textrm inside math mode very useful.
I particular I use it when I need to add hyphenated units at the end of
an equation, e.g. L=10 kN-m.
\mathrm will substitute the longer minus sign while \textrm leaves the
short hyphen
