[Chimera-users] How to hide/show sets of 'named selections' ?

I have a model with multiple proteins. Each protein chain is split into a separate pdb file (and so separate model). I have selected domains of some proteins or complete chains or others and assigned names to them from the 'namesel' command. I am unable to select multiple named selections at a time to hide certain selections. Could you please let me know how to hide/show groups of named selections. Thank you, Ajith
