Hello, would it be possible to assign a keyboard key to a joystick button, for example, the Num Lock key to button 3 on the joystick? Thank you in advance for your reply.

Easiest way is to use the "Virtual Event" section on the button assignment dialog. The most reliable and flexible is to use scripts - on the script editor there is a button "Insert VKey" to help you with this.

The reason why scripts are better is that you have control over timing and you can use the FOCUS command to target a specific application with the key press (otherwise the one currently "in front" will eat the keyboard event).

Thank you for your reply. Would it be possible to have a basic example, as I'm not good at cryptanalysis at all? Thank you in advance.
