Basics
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:
For markup languages, IntelliJ IDEA retrieves reference from the language specification according to the Document Type setting.
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 an e-mail address opens the default mail client.
Viewing quick documentation
To view documentation for a symbol at caret, do one of the following
- On the main menu, choose .
- Press Ctrl+Q.
- Provided that the check box Show quick doc on mouse move in the editor settings is selected, just move your mouse pointer over the desired symbol.
When you explicitly invoke code completion, then quick documentation for an entry selected in the suggestion list can be displayed automatically. The behavior of quick documentation lookup is configured in the Code Completion page of the Settings/Preferences dialog.
To change the font size of quick documentation, do one of the following

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, changing 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.
