Menu-Shape-Actions

** Intro:
I have been volunteered to complete a year long project of using Visio to display our corporate infrastructure. My knowledge base is 2 months of intense OJT.

** Question:
I have recently come across some shapes that have right-click options I want to add to my newly created shapes. This questions how to add 'Actions' to the Menu Bar - Shapes pull down and how to add additional right-click options to shapes.

** Situation:
With a newly created shape highlighted, I select the MENU BAR, SHAPE and the bottom of the Shape pull down options is 'Center Drawing'.

With a found shape highlighted, I select the MENU BAR, SHAPE and the bottom of the Shape pull down options is 'Actions'.
-
I noticed the difference when right-clicking the found shapes and seeing 'Show Label' or 'Hide Label at the top and 'Properties' at the bottom. The label selection brings up the Shape Name and Properties brings up the Shape Data.
-
I have searched and experimented until I am blue in the face to discover how to add Actions to the MENU BAR, SHAPES pull down options and as well as add these Actions to the right-click of a shape. ...Note; When selecting the 'Actions' option under SHAPE it shows the same options found when right-clicking the shape, I think they are linked.

Thank you very much for your assistance.
