The following table lists known Ribbon control limitations according to the WCAG 2.x standard:

WCAG 2.x Criterion	Exception Description
2.1.1 Keyboard (Level A)	The following keyboard operations are unavailable: When ribbon controls are placed within both main and child panels of a DockLayoutManager control, the main panel’s ribbon control intercepts the Alt key press. Because of that, you cannot navigate to the child panel’s ribbon control. Focus the Expand Ribbon button. Execute a RibbonSplitButton’s action. Navigate through BackstageViewControl items.
2.5.3 Label in Name (Level A 2.1 only)	The RibbonGallery items do not provide assistive technologies with accessible information.
2.4.7 Focus Visible (Level AA)	Focus indicator is visible in any keyboard-enabled user interface except for the following cases: When a disabled item is focused. When a RibbonDropdownGallery is focused.

Note

Accessibility features of your application depend on implementation (your use of Ribbon API). Your application may not require or enable user actions listed above. The limitation list may also be incomplete. Test all required user functionality to ensure accessibility compliance.

A user can use the following keys or shortcuts to interact with the Ribbon control:
