OK, I've just updated this documentation. There actually is no "yes" option, a more clear version of my snippet above would have set :eval to nil when not in export. Any value of :eval which is no "never" or "no" will result in the default behavior as determined by org-confirm-babel-evaluate. > > 2) Is there a similar variable I might test to check whether it's currently > doing an explicit C-c C-c action?
