Step by step instructions for blindly activating usb debugging. Samsung Galaxy S7

[Android Central Question]

I recently dropped my galaxy S7 on the ground and the entire screen blacked out and the screen is unresponsive. I have very important files to recover such as music and contacts, but I cannot do any of this without enabling usb debugging. So I am hoping that someone may provide me step by step instructions for how to activate usb debugging with a KEYBOARD. I found out you can connect a keyboard to your phone, so I figured I should give it a shot. It would mean so much to me if anyone helps. I have the nougat version, if that would help with the instructions.
