I have used it to bring an old Nostromo Speedpad2 back to life. And it's FREE!!

Solution 3:

Simply connect your keyboard.

When you connect it, whether wirelessly or via USB cable, it will go through the process of identifying the keyboard type.

There are a couple of conventions you have to remember...

• Control = Control
• Option = Alt
• Command = windows key
