I often attend Teams sessions with a small notebook screen. When someone shares their screen, I can hardly see anything. I would like to zoom the content without having to keep asking the sharer to do it. However, using Ctrl and Plus/Minus keys only changes the Teams controls, not the shared content. Isn’t there a way?
Yes, there is – it’s just not documented by Microsoft. In fact, the “official” zoom shortcuts are only for enlarging the controls, such as the buttons at the top. On the other hand, the main window with the video tiles or the shared screen of a participant only enlarges briefly and then jumps back to the original format.
However, if you have a mouse with a scroll wheel, you can use it to zoom the shared image content, this only affects your Teams client, nothing changes for all other participants: move the mouse pointer over the area with the shared content and move it Mouse wheel up and down on Windows while holding down the Ctrl key (macOS: Command key) to choose the zoom level. You can now move the naturally reduced visible image section by holding down the left mouse button. The controls of the Teams interface will retain their original size.
