Keyboard combinations (also key combination, keyboard command, hotkey, shortcut Key, shortcuts, key sequence) are simultaneously or successively pressed keys.
One of the most common keyboard shortcuts is CTRL + ALT +DEL.
This combination was originally used by IBM to reset or reboot the computer.
Under Mac OS X, this key combination has no special meaning, since a reset is triggered by the Cmd+Ctrl+Switch On key or by a special reset key.
The shortcut achieved great fame due to the "Blue Screen of Death", which brought the user to the brink of despair (because nothing worked anymore) and contained a hint on how to restart the computer.
Few people know that this combination was a mistake.
The developer of the IBM keyboard did not want to provide Microsoft with a single button. Therefore, the combination of CTRL + ALT + DEL was chosen.
When in later versions of Windows the Blue Screens became less common, Microsoft took over the combination to reach the login screen or the task manager.
