As far as I am concerned, when I have = to add a text to a math formula I use \mbox, as in the example

\startformula
A :=3D \left\{f : {\Bbb = R}^2 \longrightarrow {\Bbb R} \; ; \; f \mbox{ is measurable and } =  \int_{{\Bbb R}^2}|f(x)|dx < \infty \right\}.
\stopformula

The advantage being that if the above formula appears in an = environment such as a Theorem (where the text is typeset in italic, or = slanted) the text in the above \mbox will be also in italic or = slanted.

I = don't think it would be a good idea to add new commands to treat text in = a math formula: the existing possiblities are more than satisfactory, = and moreover situations where one has to add text to a formula are not = that common. So using a command like \mbox, or \text, or \mathtext, or = whatever, is not that time consuming.

Best regards: OK

Hi Alan,

1. The correct way to use \mathrm is {\mathrm ...} because it is a=20 switch like \rm for text mode.

2. \mathrm is the wrong method to write text in formulas because the=20 command changes only the math alphabet. This means no ligatures, kerning or other characters like umlauts.

3. The correct way to write text in math mode is \mathtext (which has=20 the synonym \text) or \mathword. To change the style of the text you can use \mathtext{\it =E2=80=A6} or \mathtextit{=E2=80=A6}.

Hello = ConTeXt users,

Does it drive you crazy to see TeX users write $t =3D time$?
(I = see this=20 all of the time by LaTeX users in Beamer presentations.)
One can=20 do better writing $t =3D {\rm time}$ (maybe)
or in ConTeXt = $t =3D=20 \mathrm{time}$.
Sometimes, too, I might write $t =3D = \text{time}$.

We also have the commands \mathematics{} that can be used in place of
the TeX shorthand $...$, and this also has the shortcut \m{...}.

I=20 thought that it might be useful to have an equivalent escape, to be
used as $t =3D \t{time}$. What do other users think?

OK, \m{t =3D=20 \t{time}} might be a bit funky...


Alan


P.S. I=20 proposed doing this via
\let\t\mathrm
but = Hans tells me that=20 this is not good, as \mathrm{} does not give
proper font = processing,=20 so implementation of \t{} would be something
different..._______________________________________________________________= ____________________
