How to Add Number Keys to the Windows 10 Keyboard

Not all keyboards are the same. The physical keyboard changes according to the key layout they support, For instance,, the Apple keyboard is very different from the Windows keyboard. A large keyboard has a dedicated number pad and a small keyboard is removed to shrink the size. Users can use numeric keys on the top of the letter keys to enter numbers. Some applications force you to use a row of numeric keys (numpad) in this case, you can use AutoHotkey to add number keys to the keyboard.

When you press a key, your operating system will recognize it via a virtual key code. Each key has its own code depending on the keyboard layout you added. If you need to add numeric keys to the keyboard, you'll have to make the operating system realize that the number key you're pressing is actually present on a dedicated keyboard.
