The documentation on the website is a community driven wiki (so please
contribute as you learn things). Personally I add to it as needed to
reply to developer questions. The commercial docs are more complete
(indeed only recently were operations on the wiki).

That is fine; there is a menu contribution you can add to your menu
that will display the operations for that category:
1) if the category only has one operation it is displayed as is
2) if there are more operations in the category they will be displayed
as a submenu
To meet the eclipse ui guidelines we should cap the submenu at 10
items and have an "Other..." dialog allowing the user to choose
between other operations in that category.

The Edit > Operations dialog is there to met the eclipse ui guideline
"other" requirement; allowing users in the current perspective to
access all operations irregardless if the perspective author has
included the operations in a menu or not.

Nothing much, need to look at the source code. I took a couple
minuets and hunted down the shapefile operation menu contribution and
added it to the following page:
