Keyboard keys (buttons) typically have a set of characters [[Engraving|engraved]] or [[Printing|printed]] on them, and each press of a key (or combination of keys) typically corresponds to a single written [[symbol]] or or other [[interrupt request (PC architecture)|interrupt request]].<ref>{{cite book |title=New Directions in Behavioral Biometrics |isbn=978-1315349312 |author=Khalid Saeed |date=2016}}</ref> While most keyboard keys produce [[Letter (alphabet)|letters]], [[Numerical digit|numbers]] or symbols ([[character (computing)|characters]]), other keys or simultaneous key presses can prompt the computer to execute system commands, such as such as the [[Control-Alt-Delete]] combination used with [[Microsoft Windows]].<ref>{{cite web |website=SlashDot.org
