SysReq+Key

SysReq Key

What is it and what it is doing on the same key as Prt Scr?

SysReq stands for System Request, which at one time was used to get the attention of a mainframe or central computer. Users of older IBM consoles would press the SysReq key to ask the central computer to permit input.

If you press the SysReq key do not be surprised if nothing amazing happens

Linux users can configure our mystery key to provide functions for system debugging and crash recovery, etc. but there it’s value ends.

Note:- Not all keyboards have a SysReq key, so if you do not have one, you can consider yourself up to date
