### `options: FocusableToolbarOptions`

Options of a focusable toolbar view:

* `isContextual`: Marks the higher priority toolbar. For example when there are 2 visible toolbars, it allows to distinguish which toolbar should be focused first after the `alt+f10` keystroke
* `beforeFocus`: A callback executed before the `ToolbarView` gains focus upon the `Alt+F10` keystroke.
* `afterBlur`: A callback executed after `ToolbarView` loses focus upon `Esc` keystroke but before the focus goes back to the `origin`.
