The ToolBar is a single tab stop component. All focus movements inside the ToolBar are managed according to the logic of the roving tabindex. When the user navigates through the tabs, the ToolBar focuses either the first tool or the tool that was focused last.
Keyboard ShortcutsFor scenarios where inputs, or comboboxes appear in the ToolBar, you must wrap them in focusable wrappers. To activate the inner component navigation, the user must press Enter. To return the focus to the wrapper and activate again the TolBar navigation, the user must press Esc.
For nested ToolBar components, refer to their respective keyboard navigation specification. The CommandOverflow menu must acquire the same behavior as the DropDownButton.
