Summarize the following:
Click or double-click the Microsoft Edge app icon, which resembles a blue (or white) "e". Keep in mind that, if you want to change the size of your web browser's menu items, you'll need to use your computer's Magnifier feature. It's in the top-right corner of the window. A drop-down menu will appear. In the "Zoom" section of the drop-down menu, click the - icon to zoom out or click the + icon to zoom in. Unlike many web browsers, using this menu to zoom in or out on a web page will also apply the zoom to other webpages visited in Edge.

Summary:
Open Microsoft Edge. Click ⋯. Zoom in or out.
