Yes Susan, you are right, I think my confusion was in the naming of the actions,
as you can see here:
http://wiki.modxcms.com/index.php/Manager_Actions .
And for each action, a page is loaded to perform it...
and just like that, with your help, I answered my own question.
so for: ’27’ => ’Editing document’,
the editing page of the document (now resource) is loaded on the right.
In Revo, we select the Action by selecting the page in a download menu and
doing something with it... or applying a rule or something...
The fog is starting to lift...
here comes the sun ....
