FWIW, in the original v.digit(1) (and present in the KerGIS version)
was the "widen window" option. It's zooming out by displaying a color
rectangle representing the whole map with a rectangle wire locating the
current window. Then you only select another window knowing both the
whole extend, and where you were before.
It's far more handy, since it's simpler to zoom out loosely, and then
zoom in precisely.

I didn't understand why this was nuked in GPL GRASS version.
