Often, I need the TO::fieldname copied as text. In an application with LOTS of TO's that have similar naming structures it can be a chore to find the right one.
I think it'd be nice to have the ability to select a field on a layout and either via the Inspector of a variation on the Copy command get the TO::fieldname on the clipboard as text so that it can be used elsewhere.
Here's the link to the Idea.
