How Do I Condition an Operation to Be Executed Only When the End User Tabs from One Field to Another in a Certain Direction? (Magic xpa 4.x)
Most of the time, the logic associated with a certain field should execute whether the cursor is moving up the screen or down it, since in a Windows environment users tend to click wherever they feel like. However, for more keyboard-centric applications, you can specify whether logic is executed according to the direction of the cursor flow. You do this using the Flow() function.

Flow('N') will return TRUE if the user is tabbing forward into a field. Flow('P') will return TRUE if the user is moving backward into it.
