Map Tip Action Context Menus

I want to perform a SetLayerDefinition on a second layer using a attribute of the first layer via a map tip.

 

 

Radio Towers - map tip - "Show Radio Coverage - Set Layer Definition and make Coverage layer visible.

 

 

I'm currently stuck on how you use the {Context} token.

 

 

The map tip has a "Show Coverage" on it and I have an attribute in my workflow that I need to pass the details of my selected map tip feature to.

 

 

What is the attribute type?  Graphic?

 

 

There's not a great deal of help re Map Tip Action Context Menus.
