annotate include/SDL_keyboard.h @ 3914:4fd12011d8d6 SDL-1.2
Quartz code should use F13, F14, and F15 keys instead of PrintScreen,
ScrollLock, and Pause, since that's what's on the standard Apple keyboards
(minus the laptops, which have neither set). Ideally we'll find a better way
to distinguish this...the keys being replaced would be correct on a USB
keyboard for Windows. Sigh.
Fixes Bugzilla #301.
