__UI_KeyHit is a variable of type LONG INTEGER that holds the scan code of the last key pressed by the user. Positive values mean a key was pressed, negative values indicate a key was released.

This variable can be accessed anywhere, but it's usually manipulated in [[KeyPress]] event handlers, especially for [[Text box]] controls, as it can be used to change the key presses actually sent to the control.
