# accessibility.keyboardNavigation.order

Order of tab navigation in the chart. Determines which elements are tabbed to first. Available elements are: `series`, `zoom`, `rangeSelector`, `navigator`, `chartMenu`, `legend` and `container`. In addition, any custom components can be added here. Adding `container` first in order will make the keyboard focus stop on the chart container first, requiring the user to tab again to enter the chart.
