The principal means of moving the focus using the keyboard is by pressing the Tab key (or pressing the Shift+Tab keys to move the focus in the opposite direction). The tab order determines the order in which the focus moves from object to object. The following points may be helpful in understanding the tab order:

• The tab order for browser objects and panes is preset and fixed.
• The tab order for main menu items follows the order in which they are seen on the screen (defined in the Order column in the Menu window).
• The tab order for columns within a pane follow the order as set in the Order column, which is found in the bottom pane of the Data Window tab of the Change Control Properties dialog box.
• When setting values for tab order, the order runs from the lowest non-zero integer value to the highest. A value of zero forces the focus to go to this column last. A value of negative one (-1) forces the focus to skip the column.
