[Chimera-users] Making aliases persist

I have some students this summer who are using Chimera to check out ligand anomalies in the PDB, and have fallen in love with the 'alias' command, no surprise. Is there a way to have them persist between sessions, or save them in the preference file somewhere? I imagine piling them all into a file and then having them 'read' it each session would work, but I thought I would see if there is a better way. Thanks, Jeramia Ory
