The correct answer is Switches between open applications.

Key Points

  • Pressing Alt + Tab on a computer keyboard allows users to quickly switch between open applications or windows.
  • This shortcut provides a visual display of all currently running applications, enabling users to select the desired application for switching.
  • The functionality is supported on Windows operating systems, making multitasking more efficient and seamless.
  • Holding down the Alt key while repeatedly pressing Tab cycles through the list of open windows in order.
  • This feature is particularly useful for users managing multiple tasks or applications simultaneously.

Additional Information

  • Task Switching: The Alt + Tab shortcut is a common example of task switching, a feature that enhances productivity by reducing the time required to navigate between open programs.
  • Snap Assist: On modern Windows versions (e.g., Windows 10/11), Snap Assist can be used alongside Alt + Tab to organize open applications into split-screen views for better multitasking.
  • Task View: Windows also offers a ""Task View"" feature (Win + Tab) that provides a broader overview of open applications and virtual desktops, complementing Alt + Tab functionality.
  • Keyboard Shortcuts: Keyboard shortcuts like Alt + Tab are designed to improve workflow efficiency by minimizing reliance on mouse navigation.
  • MacOS Equivalent: On MacOS, the equivalent shortcut for switching between open applications is Command + Tab, offering similar functionality for Mac users.
