How can I increase brightness on Mac without Mac keyboard I’m using a MacBook Pro and I broke it a while back. So, the keyboard doesn’t work on the laptop. I hooked up a keyboard to the USB port so I can still use it. I’m using a Dell keyboard.

Last night I wanted to listen to music without the brightness of the screen. So without thinking I turned the brightness off. Now I can't get the screen back so I was wondering if there's a way I can use the Dell keyboard to get the screen brightness back?
key: "scroll lock" to decrease brightness
key: "pause" to increase brightness
