I’m back to an attempt to migrate my old mkii project to lmtx One thing I haven’t been able to find yet is how to use the blackboard font. {\blackboard Q} Doesn’t do anything. It also doesn’t give an error.

{\blackboard Q}

Doesn’t do anything. It also doesn’t give an error.

Hi Gerben, it only seems to work inside math: \starttext \dorecurse{26}{$\blackboard\characters{\recurselevel} \Characters{\recurselevel}$} \stoptext I hope it helps, Pablo -- http://www.ousia.tk

Hi Gerben,

it only seems to work inside math:

\starttext \dorecurse{26}{$\blackboard\characters{\recurselevel} \Characters{\recurselevel}$} \stoptext

I hope it helps,

Yes, the new \blackboard command works, so $\blackboard{Q}$ works. Thanks. Feature request: make sure that the new \blackboard switches math mode on/off if necessary. Not a big deal though. The fix is simple. Adding the info about math mode might also be helpful here: https://wiki.contextgarden.net/Blackboard_bold https://wiki.contextgarden.net/Blackboard_bold G

The \blackboard command is a switch like \it, to keep it local to a single character put the left brace before the command. $Q {\blackboard Q} Q$ Wolfgang

$Q {\blackboard Q} Q$ also, it is an math alphabet switch (one of the math alphabets)
