KeyPress

The KeyPress event occurs when a control has focus and the user presses any key on the keyboard. The following variables are made available:

• __UI_CtrlIsDown
• __UI_AltIsDown
• __UI_ShiftIsDown
• __UI_KeyHit

The __UI_KeyHit variable can be modified to pass different values to the control that has focus, as the KeyPress event is triggered before the key press is actually processed.
