Occasionally when viewing a web page, you might need to zoom in or out to view the content more appropriately (photo detail or fine print). There is a simple keyboard shortcut that works with most web browsers, including Google Chrome, Microsoft Edge and Firefox. Hold the Control key (Ctrl) and then tap the + key to zoom in, or the – key to zoom out. To return to the default size, hit Ctrl+0. Same on Macs, but hit Command (Cmd), not Ctrl.
