SENDSCANKBD label | var
Remarks
Label |

The SENDSCANKBD statement can send multiple scan codes to the PC.
The label is used to specify the start of the scan codes. The first byte specifies the number of bytes that follow.
You can also send the content of a variable. This way you can send dynamic information.
You need to make sure you send the make and break codes.
The following tables lists all scan codes.
