Dr. Razzak,
Can this new property be used to store the data in the variable without
having to leave the field? Can the escape key be used to store the data
in the variable?

Did you know that you can use the new "On Key Press" EEP to
execute a defined code while start typing a character in DB
Edit or Variable Edit control?
Use "On Key Press" EEP, an event handler to make something
happen as a result of a single character key press.
The Key parameter in the On Key Press event handler is of type
TEXT; therefore, the On Key Press event registers the ASCII
character of the key pressed. Keys that don't correspond to an
ASCII Char value (Shift or F1, for example) don't generate an
On Key Press event. Key combinations (such as Shift+A), generate
only one On Key Press event (for this example, Shift+A results
in a Key value of "A" if Caps Lock is off).

is also available at:
