Hello, which board are you trying to use? Only certain boards work with keyboard.h.

edit: I see you are using an arduino uno, that board will not work because it does not have native usb. You have to have a board that has native usb to use that library.

Yeah I finally realized I needed to install a keypad in my library... rookie mistake lol

Yep, "Keypad.h" is a very commonly used, but not bullt-in, library.
