# Monitoring Windows in a Scalable Window

You can set Windows to appear in a window that can be resized to any size so that the content scales in size with the window. This is called **Picture in Picture** mode. This mode can be useful if you want to monitor applications and other tasks running in Windows as you work in macOS.

To switch to Picture in Picture mode:

* From Window mode, choose **View** > **Enter Picture in Picture**.
