Mstn has put a lot of effort into schemas that allow the user to access all kinds properties displayed in the Properties Panel.

The Properties Panel is also used to drill down into nested elements.

It would be great to allow the user to extract the expression that accesses the property using a right-click menu. The user would select or hover over the Property in the Property Panel, right-click to get an option to copy the expression.

The expression can then be pasted into another tool like the Items Expression Builder, Tables, Disply Rules or Property-based Annotation tool.

The extracted expression should also include for any code required to drill down to the nested element so that users do not have to figure this out on their own.
