Hello,
I've some troubles with jsMath's fonts.
For example, when I put : /Bbbk command, it says "unknown control sequence /Bbbk"
I searched on google and I arrived to AMsextention but I've installed it.

It is not the only one command which doesn't work.
(/nolimitsu, ...)

How can I do ?

Thank you

As for \nolimitsu, I don't know that macro; cah you say what it is supposed to do? Perhaps I can then tell you how to define it yourself.

The macro is \operatorname{Im} and corresponds to the image of function (like the kernel with \ker)
I use mathtype for Tex files.

The jsMath's answer is "unknown control sequence \nolimitsu".

Thank you very much.

OK, now I see it. It turns out that there is a missing space in the implementation of \operatorname and so the \nolimits macro that it inserts is being combined with the characters that follow it. Try adding a space after \operatorname{Im} and see if that takes care of it for you. I will fix the \operatorname macro in the next release of jsMath.
