Show documentation pane within IntelliJ window


I used to have a pane on the side of the IntelliJ 2019.3 window showing Javadoc for currently selected class name. That pane has disappeared. How do I get it back?

I found this Code reference information page on the IntelliJ site, but it does not help. It shows a "gear" icon in the Quick documentation windoid that might do the trick. My my IntelliJ offers no such "gear" icon.


Solution

    1. Select the name of a class in the source editor pane.
    2. Choose View > Quick Documentation.

    The pane appears on the bottom right of the IntelliJ window.

    Choosing View > Quick Definition (rather than Quick Documentation) shows the documentation in a windoid. To fill the pane on the side, choose View > Quick Documentation as described in step # 2 above.
