Hello,
PROG2 and PROG3? That's so mundane! Fair enough, I've checked in
linux/input.h and couldn't find exactly fitting code keys
(SWITCHVIDEOMODE, VIDEO_NEXT, VIDEO_PREV are not exactly about
rotation). At least, it would be worth adding a comment after each line
about which key does what, so that it's not necessary to read the
changelog to know!
