Show Type of Selection new
It often happens that during development you'd like to know what is the type of a Scala expression. This can be very handy when 'debugging' a type error, for instance inside a for comprehension, or a pattern match.
Similarly to the hover window, you can invoke the Show Type command on any expression, and get back the type of selection. Of course, this relies on the expression being type-correct.
If you choose Show Type an overlay window will appear, showing the inferred type of the selection.
