Google szerint szomorú lesz a SysRq billentyű történetének folytatása (a PrintScreen-é nem feltétlenül):
"The SysRq was the “84th key” added when the 83-key PC/XT keyboard became the 84-key AT keyboard.) Unless programmed by a particular application, the SysRq key does nothing in most operating systems, including DOS, Windows, and OS/2. The SysRq key has different "hooks" into the system BIOS (basic input/output system, the interface between the software and the low-level functions of the computer) from the other keys on the keyboard. IBM evidently included this key to facilitate task switching in future operating systems – that is, to allow either switching from one task to another (as on a mainframe computer), or interrupting all tasks and returning control to the keyboard. As it turned out, the developers of Windows didn't use SysReq when implementing task switching. Some new keyboards no longer feature this key, and its days seem numbered."
