Unzoom in views?

Is it possible to somehow unzoom from the views (where there is an option to zoom in with clicking/selecting an area in the plot area). I know it is possible to click on fit to size, but usually I just want to go one step back. (I tried: right click, middle click, click with both left and right, holding Ctrl, Shift, Alt; what did I missed? Using Windows.)
Thanks, gabor
