Alt Key Combinations
The Alt key is well known as part of the Control-Alt-Delete key combination, which in some operating systems brings up a task manager. If you use Mac OS, Alt+Cmd+Esc is used almost the same way. The X Window System also uses Control-Alt-Backspace, which usually causes the X server to shut down or restart.
Other well-known combinations which the Alt key is part of include Alt-F4, to close a window, and Alt-Tab, to switch between windows. Additionally, in many traditional GUI environments, including Microsoft Windows, Alt is used to access pull-down menus.
