These days, keyboards <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/general\/\" data-internallinksmanager029f6b8e52c=\"3\" title=\"General\" target=\"_blank\" rel=\"noopener\">general<\/a>ly combine the SysRq key with the Print Screen (or Prt Scr) key. To actually invoke the System Request key, you\u2019d need to press Alt+SysRq.<\/p>\n<p>This key was meant for invoking low-level operating system functions. it behaves differently from other keys on your keyboard \u2013 when you press this key, your computer\u2019s BIOS generates a special interrupt that tells the operating system the key was pressed. The operating system can listen for the event and do something special.<\/p>\n<p>These days, most operating systems and programs will simply ignore this key-press event. One notable exception is Linux, where the \u201cMagic SysRq key\u201d can send commands directly to the Linux kernel to help recover from crashes and debug the operating system.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2012\/07\/xsysrq-key.jpg.pagespeed.gp+jp+jw+pj+ws+js+rj+rp+rw+ri+cp+md.ic.40a6CeQSCD.jpg\" alt=\"sysrq key\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p><small>Image Credit: <a rel=\"nofollow noopener noreferrer\" target=\"_blank\" href=\"http:\/\/www.flickr.com\/photos\/solylunafamilia\/3016899983\/\">solylunafamilia on Flickr<\/a><\/small><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Scroll_Lock\"><\/span>Scroll Lock<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Scroll Lock is a toggle, just like Caps Lock and Num Lock \u2013 on some keyboards, Scroll Lock may also have a dedicated light.<\/p>\n<p>Scroll Lock was designed for older, text-mode environments, which had a small amount of available screen space. Pressing the arrow keys normally moved the text-entry cursor around, but people wanted a way to scroll up and down through the contents of a text screen.<\/p>\n<p>When Scroll Lock was enabled, the arrow keys would scroll the contents of the screen instead of moving the cursor.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" style=\"background-image: none; margin: 0px; padding-left: 0px; padding-right: 0px; display: inline; padding-top: 0px; border-width: 0px;\" title=\"image\" src=\"https:\/\/www.howtogeek.com\/wp-content\/uploads\/2012\/09\/image282.png.pagespeed.ce.5kjBM3CE92.png\" alt=\"image\" width=\"643\" height=\"330\" border=\"0\" onload=\"pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\" onerror=\"this.onerror=null;pagespeed.lazyLoadImages.loadIfVisibleAndMaybeBeacon(this);\"\/><\/p>\n<p>With modern graphical environments that include scroll bars and mouse wheels, this behavior is no longer necessary \u2013 in fact, most programs will ignore the Scroll Lock key entirely.<\/p>\n<p>One notable program that continues to obey Scroll Lock is Microsoft Excel.

When you press Pause, the output scrolling down your screen will stop. Depending on how the program is written, this may also pause the program\u2019s execution. Press another key after pausing and the program will continue.<\/p>\n<p>The Pause key can also pause many computers during the BIOS boot-up process.
