Quick documentation look-up

tip

RubyMine can show documentation automatically only when you invoke completion explicitly with Ctrl+Space.

2. Select the Show the documentation popup checkbox and specify the elapsed time.

To change the font size of quick documentation

• Alternatively
  In the Settings/Preferences dialog Ctrl+Alt+S, click General under Editor and select the Change font size (Zoom) with Ctrl+Mouse Wheel checkbox.

Documentation window

The Documentation popup 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 Documentation popup turns into the Documentation tool window, with the corresponding sidebar icon, and more controls.

To switch between the Documentation popup and the Documentation tool window, use Ctrl+Q.
