Seems to work in latest code, see: http://jsfiddle.net/oysteinmoseng/bp81738j/1/show/.

@SummerLi Can you verify that this works for you? The latest code can be found at http://github.highcharts.com/bugfix/modules/accessibility.js

@oysteinmoseng I can still repro this with the latest accessibility.js.

I've attached above demo zip file, the area chart script is: Highcharts_Demo/Highcharts_Demo/Accessibility_v6.0.2/area-basic/index.htm

This was not an issue with area series specifically, but an issue with the default behavior for skipNullPoints (now enabled by default) and pointDescriptionThreshold (now disabled by default, and more predictable behavior for keyboard navigation when enabled).
