Answer 1

The correct answer is Switches between open applications.

Key Points

The Alt + Tab keyboard shortcut is widely used to switch between open applications in modern operating systems like Windows, macOS, and Linux.
Pressing Alt + Tab displays a task switcher interface, showing thumbnails or icons of currently running applications.
Users can hold the Alt key and repeatedly press Tab to cycle through the open applications.
This feature improves productivity and multitasking by allowing quick navigation between multiple tasks without using the mouse.
It is supported by most graphical user interfaces (GUIs) and is a fundamental feature of modern operating systems.

Additional Information
