Hi Jean-Paul,

   I don't understand your use-case, "fast checking"?

   But here's how to do it using a new command called "zonesel" in 
Chimera 1.6 daily builds.


If I want to show the part of model #1 within 10 Anstroms of any atom in 
model #0

     zonesel #0 10 #1

That just selects the near atoms, then to show just those

     show sel

And if you want only to show ribbons for that near part

     ~rib ; rib sel

This could all be done on one line

     zonesel #0 10 #1 ; show sel ; ~rib ; rib sel

This command is not in Chimera 1.5.
