I have a 2010 macbook pro that I use with an external cheap windows keyboard 103 key (im a college student) when i use it with an external display. I have my function keys set to be fkeys and not the default apple media keys.
I was pressing the pause/break key, print screen key and the scroll lock key, and noticed that they were triggering brightness changes like the media keys would.
Does anyone know the default keybinds for this. I was wondering if there were any other weird issues like this that anyone knows of.
