Vertical Review is a separate view part in the Editor. With a translation active in the Editor simply choose View -> Vertical Review on the menu in Studio to open it. You will get a view-only display of a set number of segments at a time, with the active segment showing both source and target, a bit like the old Trados TagEditor. You can browse through your translated files in Vertical Review to review the translation in a top-down vertical view or work away as normal in the standard Editor with Vertical Review as an additional segment view. With Vertical Review you also get keyboard shortcuts, Ctrl+Shift+PgUp and Ctrl+Shift+PgDown, for moving up and down through all segments, regardless of segment status. The font and background colours can be set to optimise readability.
