How do I change my keyboard from window to window?

You can quickly switch between open windows on your computer using keyboard shortcuts. Here's how:

1. Press and hold the Alt key ([Alt]).
2. While holding Alt, press the Tab key ([Tab]) once. This will bring up a window switcher.
3. Keep the Alt key pressed down. Each time you press the Tab key (or use the arrow keys), the selection will move to the next open application in the window switcher.
4. Release the Alt key to open the application that is currently selected in the window switcher.

This method works across different operating systems like Windows, and is a very efficient way to navigate between different applications.
