This week we will release new major feature for the RadRibbonBar – keyboard access. KeyTips provide keyboard access to every control in the Ribbon. They are activated by pressing the ALT key, following by the key for the button you want to activate. KeyTips are very well explained at the Microsoft’s fluent UI guidelines, you can read more about KeyTips on msdn… This feature is in the Required section from the Ribbon specification, but it’s nature and hard implementation details was preventing us from implementing it sooner.
