Grid Pane Navigation Bar
For grid panes with more rows than a single page can accommodate, a navigation bar appears at the bottom of the grid pane. By using it, you can go to the first, previous, next, or last page of the pane.
If you press Tab when the focus is on the navigation bar, the focus shifts to the "First" or the "Next" arrows. The "First" and "Previous" arrows are disabled when the first page of the grid pane is displayed. Similarly, the "Next" and the "Last" arrows are disabled when the last page is displayed.
The keyboard shortcuts listed in the table Keyboard Shortcuts for Grid Pane Navigation Bar are applicable only to the grid pane navigation bar.
