As you know, you can open the a List of C/AL Expressions with F5 on the SourceExpression Property. Unfortunately you cannot insert a variable directly in the SourceExpression by selecting a variable and pressing <Enter>.
However you can Copy the variable with Ctrl-C in the List and paste it with Ctrl-V in the SourceExpression property.
Better than nothing.
