[Chimera-users] selection of some chain but not some particular residue

Hi All I am new to Chimera and i have hard time finding commands like how to select some chain and exclude 1 or 2 residue in that chain? also i have a protein with 2 chain. how can i make different model for different chain or different portion of same chain so i can perform some action like clipping on these model independentaly? can any one please help me for these problems?
