The Magic SysRq key is a key sequence that issues low-level commands related to system state in the Linux kernel, and is used in combination with SysRq and other keys. It is used for debugging in kernel development, and is often used to restart a computer when the system freezes without recovering from that state or damaging the filesystem.
In short, since it is a key that is basically not used in Windows, it often lives with other keys like the print screen key. It may be worth remembering, but as long as you're using Windows, the existence itself doesn't make sense. However, the fact that this SysRq key is displayed without erasing is also a proof that the keyboard properly considers not only Windows but also Linux as the usage environment, so 'What kind of user group does this keyboard have?'
