After screen enlarges, how do I shrink it back.

I have just noticed that the OP asked about the screen, not a window. few days ago I came across how to enlarge the whole screen but have forgotten where. Any info?

The reason why I think that enlarging the whole screen would be useful is when the pinch or the two finger tap is used, it is the content of the window that enlarges, not the window, with the result that some of the (now magnified contents) are lost (but can be seen by left/right scrolling).

Tap the mouse again and it shrinks.

On my iMac (mid 2011) I have to double tap with two fingers, and again to shrink back).

The screen zoom is holding CNTL and scrolling up. Unzoom CNTL Scroll down.

Thanks.

You can manage your your zom setting in System Preferences >> Universal Access.

Tap again. In my case I tap a bit on the right front, which works well.

Single finger, double tap if you are using a Magic Mouse.
