Smart Key Tip
One of the most important UX aspects in Ribbon UI metaphor is the keyboard accessibility.
Ribbon UI changes the paradigm of the classic dropdown menu into a modern, visually-appealing
tabbed command interface – while at the same time continue to support keyboard accessibility
through the "Key Tips" feature.
UXRibbon implements the key tips feature according to the latest Office's ribbon
specification. The key tips feature is supported on all controls that implement
IRibbonKeyTipAction interface such as UXRibbonButton, UXRibbonDropDownButton, UXRibbonToolBarButton
and much more. In addition, UXRibbon also supports hierarchical/nested key tips
such as in dropdown and menu items.
