Definition of Security Group Tasks & Events

Is there a document that defines each of the tasks & security events under Maintain Security Groups?

There are 1200+ items in here.  Sometimes it is self explanatory and matches a menu item in Sage, but sometimes a function requires several tasks.  We wanted to ensure that a group didn't have access to post, and we needed to set both "Post GL Batches" AND "Journal Transaction Register" to Display Only.  Also sometimes there are 2 tasks almost identical - "Reference Code Maintenance" and "Reference Codes Maintenance".  How do I know what the difference is?

It seems like there must be documentation on what each of these items does.  Anyone know where I can find it?

Thanks in advance.
