A tabstrip is a grouping element that can display different application elements on a single screen. A tabstrip consists of one or more pages and each page has a title.
To display a hidden tab page, move the focus to the title of the page and choose [Space].
Sequential element navigation works for tabstrips, which means you can move the focus forwards to a tabstrip using [Tab] or backwards using [Shift]+[Tab].
To jump to the next or previous tabstrip page, choose [Ctrl]+[PageDown] or [Ctrl]+[PageUp].
