Macro for shape appearance and disappearance

[york]

Hey,

I need a help with creating macro for shape appearance and disappearance. I have two shapes, shape A and shape B. When I do mouse over shape A, shape B should appear. Then when I do mouse over shape A again, shape B should disappear.
Instead of a shape B it can be a a text box.

I found very useful video how this is sloved in Excel :  https://www.youtube.com/watch?v=iyXj4YyCKxY 

Unfortunately I couldn't code this in Visio. I am new to vba so I've been having a trouble with defining objects. 

Every solution, suggestion or advice is more then welcome!  Thank you!
