[chimerax-users] Selecting residues in two chains

Hi Everyone, I have a .pdb file created using AF2 Multimer. It consists of two chains, B and C. Chain B is a protein with 315 residues, while Chain C is a protein with 662 residues. Each chain is modeled with structured and unstructured regions. I would like to only show residues 19-24 of Chain B and residues 1-190 of Chain C in the display window. I have tried using the information provided on the "Command-Line Target Specification" page, but I have not had any success with just displaying those ranges of residues in the display window. My goal is to highlight specific features of those ranges of residues to display their interaction. Thanks for any information you can provide. Phil McClean
