I am currently using a Macbook Pro with a Windows 7 partition to work on a Mario Rom. I know that I'm supposed to press Control-Shift-Page Down on the 8x8 tile editor to allow "Internal GFX viewing data unlocked". Unfortunately, there is no page-down key on this keyboard and I'm supposed to press ("Fn" -down arrow) to use page-down but, when I try that with Control-Shift, it doesn't work. Is there a non-keyboard way to allow "Internal GFX viewing data unlocked" from the menus on the top? I couldn't find anything. Any help is appreciated.
