[Chimera-users] Q about opening two structures in the same window

Hello, I recently downloaded chimera and have been using to view my protein homology model - mainly to show the 2 residues that could be involved in binding to a molecule inside the cell. For that purpose, I need to be able to open the small molecule (citrate or phosphate) in the same window with protein; so I can show the small molecule binds to the specific amino acid residues. But even if I open the two together, how do I pick the small molecule and move it around where I need it? Please help. Thanks, Farhana
