[PyMOL] selection function

If you have the molecules "mol01" and "mol02" open, you can type "mol_list 
= cmd.get_names()" to get the list of molecules put into the variable 
mol_list: ['mol01' ,'mol02'].

Now let's say you've got those two molecules open and you've made some 
selections within those two molecules.  The GL window will then have a 
list of objects like:  "mol01", "mol02", "pk1", "pkmol", "pkresi", ... 
"sel01", "sel02".  Does anyone know of a command analogous to 
cmd.get_names() that will return this list of objects from the GL window. 
( cmd.get_names() still returns only ['mol01', 'mol02'] )

Thanks,
