Proper keyboard navigation must be verified on JTable for the JLF LAF

The following navigation, activation and selection keyboard bindings on JTable need verification for proper operation and key binding sequences.

JTable

   Navigate In - Tab, shift-tab, control-tab, shift-control-tab
   Navigate Out - Control-tab, shift-control-tab (reverses direction)
   Navigate within -
                The discussion below is for a table (such as a typical
                spreadsheet) that allows identified or editable cell
                rectangle selection. Keyboard navigation will be
                simplified for the other, more restricted, cases.
                
        Return/shift-return - move focus one cell down/up. If only one
                cell is selected, the focus should wrap (top to bottom,
                left to right, and then back to the top, left cell for
                return) so as to traverse the entire table. If more
                than one cell is selected, the focus should wrap to
                traverse each selected rectangle in turn and then
                repeat from the beginning. Shift-return is similar but
                moves in the reverse direction.
        Tab/shift-tab - move focus one cell right/left. If only one
                cell is selected, the focus should wrap (left to right,
                top to bottom and then back to the top, left cell for
                tab) so as to traverse the entire table. If more than
                one cell is selected, the focus should wrap to traverse
                each selected rectangle in turn and then repeat from
                the beginning. Shift-tab is similar but moves in the
                reverse direction.
        Up/down arrow - deselect current selection; move focus one cell up/down
        Left/right arrow - deselect current selection; move focus one cell
                           left/right
        PageUp/PageDown - deselect current selection; scroll up/down one
                          JViewport view; first visible cell in current
                          column gets focus
        Control-PageUp/PageDown - deselect current selection; scroll
                                  left/right one JViewport view; first
                                  visible cell in current row gets
                                  focus
        Home/end - deselect current selection; move focus and view to
                   first/last cell in current row
        Control-home/end - deselect current selection; move focus and view to
                           upper-left/lower-right cell in table

   Editing Cells
        F2 - Allows editing in a cell containing information without
             overwriting the information
        Esc - Resets the cell content back to the state it was in before
              editing started

   Extending Selections in Tables
        Ctrl+A, Ctrl+/ = Select all
        Ctrl+\ = De-select all
        Shift-up/down arrow - extend selection up/down one row
        Shift-left/right arrow - extend selection left/right one column
        Control-shift up/down arrow - extend selection to top/bottom of column
        Shift-home/end - extend selection to left/right end of row
        Control-shift-home/end - extend selection to beginning/end of data
        Shift-PageUp/PageDown - extend selection up/down one view and scroll
                                table
        Control-shift-PageUp/PageDown - extend selection left/right one view
                                        and scroll table
