Sory for the late reply. Well, in my case, we are making games for kids, from age 7-11, and all games run in full screen. We dont want the kids to press escape and get MINIMAZED windows, we want to game to exit completly on ESC, or block ESC and expose an exit button in game just like all other games do. The main point here is to make Flash tehnoloty transparent.
The directX world wanted ALT+TAB blocked just to block users to get to windows while the game is running so it cant be easely cracked, or in MMORPG world, so that to pockets cant be sniffed easely. All those blocks are used to prevent bad people to do bad things to your software.
