Is it possible to prematurely stop a command issued on the command line that takes too long time?

 

I often have sessions with many (more than 20) large ribosome structures open at the same time. I sometimes mistype the restrict atom-spec2 argument for the hbonds command and ChimeraX goes through each of the structures one by one twice, which can take very long time.

 

I wish there were a flag to the hbonds command to only consider the models in atom-spec1, so that those typos does not spawn a search across all models.

 

In addition, it would be great if the code for the hbonds command could be optimized. Why iterate over all models if only atoms in one model are in atom-spec1?
