This sounds more like a question about selection. There are many ways to select, not just the menu. For example, you can select using the mouse (Ctrl-click) in the main window. If you select one atom or bond, then you can use the keyboard up arrow to increase the selection to the whole residue. Or, you can use a command like “select :32.A” (select residue 32 in chain A; first show the Command Line from the Favorites menu). Or, you can show Sequence (also in Favorites menu) and then select the residue in the sequence window. Here is the page about selection:
There is an example of using Find Clashes/Contacts in this tutorial:
Or instead of using the Find Clashes/Contacts graphical interface, you can use the “findclash” command and just name the residue directly instead of selecting it, for example to find clashes and other contacts:
findclash :32.A test other overlap -0.4 hb 0 reveal true
…or to find only the clashes, if any (unfavorable because they are too close):
findclash :32.A test other overlap 0.6 hb 0.4 reveal true
See manual for additional command options.
I hope this helps,
