The Eclipse scala plugin has a nice feature which shows you the type of a variable when you hover the mouse over it. How do I see the same information with the IntelliJ plugin?

Select expression and type Alt + =.
If you want to change the shortcut go to Preferences > Keymap
and enter "Type Info" in the search field.
In older versions, it's Shift + Ctrl + Alt + T.
