Thanks Wolfgang, that was exactly the command I was looking for!

A last question: how can one get italic greek in TEXT MODE? The following
code displays upright greek.

\starttext
\mathgreekitalic \alpha
\stoptext

The command \mathgreekitalic can only be used in math mode, when you want a italic alpha
in text mode you need a font which has greek characters (e.g. Gentium).

\definetypeface [mainface] [rm] [serif] [gentium] [default]
\definetypeface [mainface] [mm] [math]  [xits]    [default]

\setupbodyfont[mainface]

\starttext
α {\it α} \quad \m{\alpha \mathgreekupright \alpha \mathgreekitalic \alpha}
\stoptext

The \os command enables oldstyle figures in your font and the setting isn’t reset when you switch to a different font alternative.

\definefontfeature[f:lnum][lnum=yes]
\definefontfeature[f:onum][onum=yes]
\definefontfeature[f:tnum][tnum=yes,pnum=no]
\definefontfeature[f:pnum][pnum=yes,tnum=no]

\setupbodyfont[antykwa-poltawskiego]

\starttext

\starttabulate
\NC onum        \NC \feature[+][f:onum]                   1234567890 \NC\NR
\NC onum + tnum \NC \feature[+][f:onum]\feature[+][f:tnum]1234567890 \NC\NR
\NC onum + pnum \NC \feature[+][f:onum]\feature[+][f:pnum]1234567890 \NC\NR
\TB

\NC lnum + tnum \NC \feature[+][f:lnum]\feature[+][f:tnum]1234567890 \NC\NR
\NC lnum + pnum \NC \feature[+][f:lnum]\feature[+][f:pnum]1234567890 \NC\NR
\stoptabulate

\stoptext

Out of curiosity, how do you do that (i.e., revert back to lining, and 
tabular, figures in a table, or even in running text)?

For example, if I do this:

     \starttext
     \bf 12345\par
     \tf 12345\par
     \stoptext

the first line is bold but the second is not.  But if I do the same with 
\os:

     \starttext
     \os 12345\par
     \tf 12345\par
     \stoptext

both lines use old style numbers.  Is there a way to switch the current 
font back to lining figures without reloading the font with 
\switchtobodyfont or something similar?

Thanks,
Brian

a math font has a greek (math) alphabets which is not the same as text 
greek (it might have different shapes, different kerning properties, 
etc) ... in a similar fashion a math font has sans and monospaced and 
script alphabets

Okay Wolfgang, I thought Latin Modern also had greek characters, but
apparently not. So in math mode which font is used by default if it is not
Latin Modern greek?

You can enable lining (and tabular) figures in the table when you don’t want oldstyle figures.

For instance, in the following example I would like to keep the bold effect but with adaptation to the local alternative style (in text mode, when the local alternative style is \tf I would like the mathcommand to be \bf, when it is \it I would like \bi, when it is \bf I would like \bf and when it is \bi I would like still \bi):

You can access the current font alternative with the \fontalternative command (below is a old example I wrote a few months ago).

\def\Test

     [\fontalternative]

           it=>Italic,

> why  use math here?

It was to avoid oldstyle figures that I use by default. But finally it's
better to use oldstyle figures even in tables.

Another question about fonts. Is there a way to define a conditional
mathcommand based on the current alternative style? For instance, in the
following example I would like to keep the bold effect but with adaptation
to the local alternative style (in text mode, when the local alternative
style is \tf I would like the mathcommand to be \bf, when it is \it I would
like \bi, when it is \bf I would like \bf and when it is \bi I would like
still \bi):

\starttext
\definemathcommand[cool]{{\bfmath cool}}
text mode normal: \cool\crlf
text mode italic: {\it \cool}\crlf
text mode bold: {\bf \cool}\crlf
text mode bolditalic: {\bi \cool}\crlf

indeed, as math node lists have a completely different structure ... why 
use math here?

Character alignment in math mode

[Maggyero]

[-- Attachment #1.1: Type: text/plain, Size: 535 bytes --]

How can one use character alignment in math mode? (I am using the last
stable ConTeXt version — 2014.05.21.)


\starttext
\setupTABLE[column][first][alignmentcharacter={,}, aligncharacter=yes,
align=middle]

Figures in text mode get aligned:

\startTABLE
    \NC 0,0     \NC \NR
    \NC 0,00    \NC \NR
    \NC 0,000   \NC \NR
\stopTABLE

But figures in math mode do not get aligned:

\startTABLE
    \NC $0,0$   \NC \NR
    \NC $0,00$  \NC \NR
    \NC $0,000$ \NC \NR
\stopTABLE
\stoptext
