[chimerax-users] Doubt about "contacts" command in ChimeraX

Good evening, I am actually using ChimeraX and I am trying to figure out a command that can show me all the contacts of my ligand below 3.0A with my protein. Unfortunately, I have not found anything clear enough to do so. Is there a way to do this? Another doubt is, if I have labelled 2 contacts (i.e 2.576A and 3.149A) but I am interested in only showing the label " 2.576A", I try deleting the other contact label (" 3.149A") by selecting it and typing the "label del" command, but this will delete my label of interest as well. Is there a way of only deleting specific labels from the contacts? Any help is appreciated. Best regards, Manuel
