I think you need to read a bit the online manual (in the Help menu) to get acquainted with the basic concepts, it will spare you a lot of time if you think to use TeXmacs more seriously.

Equation environments can be numbered by choosing the “Numbered” item in the “Focus” menu. But the cursor has to be inside the environment for this to work. 

Alternatively you can click on the “IV” button in the focus bar (which is the lowest of the three toolbars you see in the GUI). Again, for this to work, the cursor has to be in the equation environment.

Give also a look at the forum (http://forum.texmacs.cn/) for many answers to common questions.

Hi Julien

Many thanks. 

It worked (sorry for the newbie question) but how can I paste it as a mathematical equation with a number assigned to it?   

Cheers

Otherwise, it will just add the code to the document. 

It’s possible to create a shortcut and add it to your my-init-texmacs.scm  if you use this a lot.
