[PyMOL] cgo_text and number of states

Hi List!

I'd like to know if I can use some character with cgo_text and how:
'&', '=3D' are some that I didn't get on screen.

BTW, where can I find more docs about it?  In Python docs?

Another question, which variable/parameter would return me the number of=20
frames/states of a trj file (MD)?

Many thanks in advance.
Cheers,
