"AddInterpretation"

"AddInterpretation" is a front end token that opens a dialog box where you can enter an expression that will be interpreted as either an InterpretationBox or as a TagBox.

This token is equivalent to the menu command Edit Expression Input Add Expression.

The expression will be inserted at the current insertion point.

To execute a front end token, you typically evaluate a command of the form FrontEndExecute[FrontEndToken[token]].
