Feature request: when in thumbnail view, spacebar for scroll

feature request: when in thumbnail view, use space bar for scrolling down / go down through the images collection.

Why? We have down arrow key, mouse wheel...

* spacebar is used in the browser to scroll down too in steps
* it is possible to scroll down in "steps" (pictureline after pictureline)

this feature is especially very useful when using a notebook with a pointing stick/TrackPoint without mouse.
