The Kendo UI Toolbar supports keyboard navigation between its items either via TAB/SHIFT+TAB or the RIGHT and LEFT arrow keys (documented here). However, there are some issues:
- While the arrow keys cycle endlessly, the user needs to be able the "escape" this cycle when using TAB, otherwise parts of the page would be inaccessible by keyboard. This "breakout" does not work when navigating backwards (SHIFT+TAB) in some scenarios as this DOJO demonstrates. Also, when focusing "After" and pressing SHIFT+TAB, the focus jumps to the splitButton instead of the overflow anchor which is inconsistent with the way TAB alone works.
- When the last visible (not-overflown) item is a separator after a splitButton, the overflow anchor is not focusable via TAB at all. This can be witnessed in this DOJO. However, when combining the items differently, everything seems to work fine.
