I thought as much -- what confused me is that his response was not among
the postings I could find in the list (perhaps he responded by private
mail). Anyway, no big deal -- not the first time I've been confused, and
won't be the last. (In fact, won't be the last today. :-)

Bad guess on my part. I looked it up: \mathrm, \mathit etc. are part of
the standard LaTeX distribution.

Same is true for me, and probably for a lot of us.

Could be -- not sure if the "no subscripts in textrm" thing is in there.
However, for what it's worth, that's not where I learned about \mathrm.
I'm pretty sure I picked it up from this group, or from some other help
source on the Internet.
FYI, if you haven't checked the math panel yet, it's a handy way to
specify a font within math mode (including roman, which gets you mathrm).
Might not be as convenient for someone who is keyboard-oriented. Another
possibility is to create a key binding to get into mathrm.
But I'm still a bit confused as to why one would want to toggle into
textrm, rather than mathrm, when in math mode.
