Mouse Echo automatically reads text that is underneath your mouse pointer. It will speak the entire item name, or if you’re on a webpage, the entire paragraph of text you are hovering over will be read.
By default, Mouse Echo will only read text if you first press the Option key. You can change the key that activates it, or you can set it to “Always On”; in this case text will be read aloud immediately as soon as the mouse is over text.
If at any time you’d like to interrupt Mouse Echo, just press the CONTROL key.
