We don't have #1, though it used to exist in Midas by pressing the  
Escape key during script execution.  I will open a feature request in  
our Trac database to get this capability back.  It will probably take  
a couple of months for me to get to it.  You'll get automated mail  
from Trac when the implementation happens.

I went ahead and implemented #2 since I thought it would be trivial.   
It turned out to be a little less trivial than I had thought, but not  
too bad.  It will be available as the "pause" command starting with  
tonight's daily builds.

I don't know what your need for these commands are precisely, but you  
should be aware that the Demo capability of Chimera offers #2 already,  
though maybe creating a demo is a little more elaborate than what you
