[PyMOL] how to show sticks for the side-chains of selected residues

[yibin xu]

Dear All,

I want to show sticks for only side-chains (CA and beyond CA) of
selected residues in the cartoon mode. Is there an easy way to do that (
my way is to use SELECT followed by showing sc but mc atoms are still
displayed)? 
Thank you very much in advance.
Regards
