Zoom in On Your Screen
When showing your screen, and especially when recording your screen, you want to zoom in. These keyboard shortcuts work on your browser window (ie: when you’re using Chrome).
Hold down the Control key (Command on a Mac) and press the plus key repeatedly to zoom in.
Control Minus zooms out.
This is an important one. Control Zero resets your zoom. If ever your screen is not showing icons or things you think it should be showing, one of your first trouble shooting tricks is to use Control Zero.
