Magnifier Usable Only with Mouse is a Chrome extension designed to facilitate web page zooming without the need for a keyboard. This tool allows users to zoom in and out by utilizing the mouse wheel while holding down the right mouse button, making it particularly useful for those who may find it difficult to reach the keyboard from a distance. The zoom method is customizable, enhancing the user experience for individuals using wireless mice.

The extension includes features such as the ability to enable or disable the scroll with mouse cursor function via the context menu. Users can also change the default right mouse button to other buttons and reverse the zoom direction based on their preferences. It is important to note that the extension may not work on certain Google pages or previously opened web pages, requiring a page reload after installation for optimal functionality.
