Quick documentation look-up

tip

PyCharm can show documentation automatically only when you invoke completion explicitly with CtrlSpace.

Quick documentation look-up helps you get quick information for any symbol that is supplied with Documentation comments in the applicable format. PyCharm recognizes inline documentation created in accordance with the JavaScript Documentation Tool format.

To view documentation for a symbol at caret

Press Ctrl0Q or select View | Quick Documentation Lookup from the main menu.

To show documentation automatically

  1. In the Settings dialog (CtrlAlt0S) , go to Editor | General | Code Completion. The Code completion page opens.

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

To change the font size of quick documentation

  • Click show-slider.png in the upper-right corner of the quick documentation window, and move the slider.

  • Alternatively In the Settings dialog (CtrlAlt0S) , 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 Ctrl0Q.
