[Chimera-users] center of rotation

[Elaine Meng]

Hi Bill,
If command "cofr sel" is too long, you could

(a) use the command "alias" to alias it to a shorter command, e.g.

alias ^blah cofr sel

which would then allow you to use the command "blah" 

or if you don't use the Command Line, (b) define your own keyboard shortcut

However, the latter requires some Python, on which I cannot advise.
