How to make error pop-up appear using keyboard in IntelliJ IDEA

Question

When using IntelliJ IDEA and writing code, and when code you wrote has an error, the only way I know to make IDEA show you the error details is to hover the mouse cursor over the problem.

But that requires moving my hands from the keyboard to the mouse. Is there a hotkey that causes that pop-up with the error message to appear, or a way to configure such a hotkey?
