Editions
   The Editions command is used to control subscription to another 
document. Selecting and holding the mouse key on Editions from the 
Edit menu activates a submenu. This submenu provides two options, 
each of which activates a dialog box. The Subscribe To selection 
dialog box allows you to specify a document to which you wish to 
subscribe. The Subscriber Options dialog box is used to specify 
the attributes of a subscription, including timing of updates, and 
cancelling of a subscription.
    A full description of the subscription process can be found in the
Macintosh System 7 documentation.
