text: "CursorNavigation allows overriding the navigation algorithm with the redirects -property. You may define angle sectors that bypass the algorithm, and instead move the cursor or focus to a predefined target object. This is useful for example implementing wrapping. Moving the cursor past the end of the button rows will wrap the cursor to the other end. The row in the bottom is done using a repeater and redirects have been set dynamically. Movement between the button rows has been redirected to go via the button in the center."
