Due to a stroke, I have had some vision impairment in that I sometimes have a hard time locating my mouse pointer on the screen. I have tried making the mouse pointer larger which helps but is still not the solution.

I am new to the Mac world and would appreciate your help.

In Windows, there is an option where pressing the CTRL key will help to identify the mouse pointer using a temporary display of several radiating concentric circles around the mouse pointer. Is there something like this on OS X?
