not rely on the previous (key) behavior3,getkeystate With a virtual key parameter, returns the state of the virtual button, whether it is pressed or bounced, or is the specific trigger state of a key such as an uppercase lock key.If the high-order bit is 1, the key is in the down state, otherwise the up state.If the low-order bit is 1, the key is triggered. For example, the CAPS LOCK key will be triggered when the drive is found. If the low-order position is 0, the key is closed and is not trig
