Workflow Transition Properties Value LIST?

[Greg Cook]

HI,

Im getting my head around jira workflows and transitions.  Properties are of interest and i have see some examples where jira.i18n.submit  is being set to sd.workflow.save

My question is what are the list of possible values you can set.  do i randomly have to know that sd.workflow.save will change the test on the submit button to Save rather than the Transition Name ( in this case it was default CANCEL , so you had two cancel buttons side by side ).

Is there a master list of the pre configured translated values?  

So far my searches have found very little information 

Any references would be super helpful

thanks
