== Modern uses ==
In [[Linux]], the [[Kernel (operating system)|kernel]] can be configured to provide functions for system [[debugging]] and crash recovery.<ref name="linux">{{cite web|title=Linux Magic System Request Key Hacks|work=Linux kernel|url=https://www.kernel.org/doc/html/latest/admin-guide/sysrq.html|access-date=2018-06-21}}</ref>  This use is known as the "[[magic SysRq key]]".

[[Microsoft]] has also used SysRq for various [[Operating system|OS]]- and [[Application software|application]]-level [[debugger]]s. In the [[CodeView|CodeView debugger]], it was sometimes used to break into the debugging during program execution.<ref name="mskb43648">{{cite web|title=Returning Control to CodeView|work=Microsoft Knowledge Base|url=http://support.microsoft.com/kb/43648|access-date=January 8, 2008|archiveurl=https://web.archive.org/web/20081108021540/http://support.microsoft.com/kb/43648|archivedate=November 8, 2008|url-status=dead}}</ref> For the [[Windows NT]] remote kernel debugger, it can be used to force the system into the debugger.<ref name="mskb900093">{{cite web|title=How to enable a remote kernel debugger connection on a computer that is running Windows Server 2003 with Service Pack 1|work=Microsoft Knowledge Base|url=http://support.microsoft.com/kb/900093|access-date=January 8, 2008|archiveurl=https://web.archive.org/web/20121021034022/http://support.microsoft.com/kb/900093|archivedate=October 21, 2012|url-status=dead}}</ref>

On modern Windows and some Linux desktop environments "[[Alt key|Alt]] + [[Print screen]]" (which is the shortcut for SysRq on most modern keyboards<ref name="modern" />) copies an image of the current active window, instead of the entire screen as Print Screen alone would.<ref>{{cite web|title=Copy the window or screen contents|access-date=March 2, 2020|url=https://support.microsoft.com/en-us/office/copy-the-window-or-screen-contents-98c41969-51e5-45e1-be36-fb9381b32bb7}}</ref>
