Auto scroll is a feature that allows a web page or document to scroll automatically without the need for user input. This can be a useful feature for long documents or web pages that contain a lot of information, as it allows users to read through the content without having to manually scroll down the page.
There are a number of different ways to turn on auto scroll. One common method is to use the keyboard shortcut Ctrl + Shift + Up Arrow (Windows) or Cmd + Shift + Up Arrow (Mac). This will cause the page to scroll up automatically. To stop auto scroll, simply press the Esc key.
