Often I need to use a field table and name in calculations but can't easily get to it via the table/field picker tools. For example - a schema with long, repetitive, not intuitive naming structures - as seen in the screen capture.
It would be a real time saver if you could select a field on a layout and with a variation on the copy command (option, ALT, etc.) get the TO::fieldname copied to the clipboard so that it could easily be used elsewhere. The function could also be an option on the Inspector panel. On the Data tab the "Display data from" box looks like it should be an editable field - being able to copy that text would accomplish the same task or having an additional button beside the pencil edit button.
