JetBrains Rider 2022.1 Help

Quick Documentation

With JetBrains Rider, you can quickly review the documentation of a symbol right in the editor. If the symbol is documented in a supported format (such as XML-docs for .NET languages), you will see all the documentation with proper formatting. Otherwise, the basic symbol information will be shown (such as full method signature or type visibility and namespace).

Quick documentation popup

By default, the Quick Documentation popup appears when you hover the mouse over any symbol. If you want to disable that and always invoke the popup explicitly, click App actions more in the popup and then click Show on mouse move or alternatively, clear the Show quick documentation on hover checkbox on the Editor | Code Editing page of JetBrains Rider settings Ctrl+Alt+S. Explicit invocation will be available regardless of this option. If you prefer to see Quick Documentation on mouse hover, you can configure the appearance delay (in milliseconds) in the Tooltip delay field on that settings page.

View quick documentation for a symbol

  1. Set the caret

    • at a symbol reference in the editor,

    • anywhere within a documentation comment.

  2. Press Ctrl+Q or choose View | Quick Documentation from the main menu . Alternatively, you can press Ctrl+Shift+A, start typing the command name in the popup, and then choose it there.

  3. In the Quick Documentation popup that appears, you can study symbol documentation and follow hyperlinks to view related documentation.

You can invoke Quick Documentation as soon as you have typed a symbol reference, this will help you make sure that you've used the correct symbol. It doesn't have to be a valid statement, a correct symbol name is enough:

  • Browser-like back/forward navigation buttons in the top left corner of the popup. These buttons appear when you choose to display the toolbar in the popup.

JetBrains Rider: Documentation tool window

When JetBrains Rider shows Quick Documentation for overridden and implemented members, the following convention applies:

  • If an overriding/implemented member does not have any documentation but its base member does, base member documentation is shown.

  • If they both are documented, the documentation of the overriding/implemented member is shown.
