Viewing Inline Documentation
Quick Documentation Lookup helps you get quick information for any symbol or just method signature information, provided that this symbol has been supplied with documentation comments in the applicable format.
IntelliJ IDEA recognizes inline documentation created in accordance with Javadoc markup.
In this case, such documentation is properly rendered in the Quick Documentation Lookup window:
The URLs and e-mail addresses specified in the documentation comments for methods are also properly rendered. Clicking a hyperlink opens the corresponding URL in an external browser; clicking the e-mail address opens the default mail client.

Toolbar of the Quick Documentation Lookup
The Quick Documentation Lookup window helps navigate to the related symbols via hyperlinks, and provides a toolbar for moving back and forth through the already navigated pages, change font size, and viewing documentation in an external browser.
When pinned, the Quick Documentation Lookup turns into Documentation Tool Window, with the corresponding sidebar icon, and more controls.
