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.

“One way to think about play, is as the process of finding new combinations for known things—combinations that may yield new forms of expression, new inventions, new discoveries, and new solutions....It’s exactly what children’s play seems to be about and explains why so many people have come to think that children’s play is so important a part of childhood—and beyond.”
—Fred Rogers (20th century)
