View | Tool Windows | Documentation

Ctrl+Q

The View | Tool Windows | Documentation menu option appears only if you have configured the IDE to display code documentation in a tool window.

Out of the box, IntelliJ IDEA shows code documentation in a popup as you hover the mouse pointer over symbols in the editor. You can change the view to use the tool window by default: press Ctrl+Q to open the popup and then press Ctrl+Q again.

This tool window is also available in Scientific View.
