PROCEDURE Object.KeyPress
LPARAMETERS nKeyCode, nShiftAltCtrl

Parameters

nKeyCode

Contains a number that identifies the key pressed. For a list of codes for special keys and key combinations, see INKEY( ).

nShiftAltCtrl

Sets a particular bit if a modifier key is held down while pressing the key specified by nKeyCode. Valid modifier keys are the SHIFT, CTRL, and ALT keys.

The following table lists the modifier key values for nShiftAltCtrl.

nShiftAltCtrl	Modifier key
1	SHIFT
2	CTRL
4	ALT

This parameter is the sum of the bits with the least-significant bits corresponding to the SHIFT key (bit 0), the CTRL key (bit 1), and the ALT key (bit 2). These bits correspond to the values 1, 2, and 4, respectively. This parameter indicates the state of these keys. Some, all, or none of the bits can be set, indicating that some, all, or none of the keys is pressed. For example, if both CTRL and ALT are pressed, the value of nShiftAltCtrl is 6.
