Hi:  I have a simple question - How do I display the lab or fixed frame coordinate axes?  I am using the windows 32 bit UCSF Chimera on my desktop.  In rasmol the command is "axes on".  I cannot find anything similar in Chimera.

Thanks for your help.  An axes display is critical if you need to know the spatial orientation wrt the lab frame.

Best wishes, Michael
