Comment 8 for bug 343674

Maybe one could use the page up and page down keys? Maybe it would make the scroll length problem easier to solve (one scroll step would be not a full visible screen size but a bit less - but I think the thickness of the missing strip should be constant for all apps). The only problem is how to compose the last two shots since the last scroll step could be much less then a full visible screen size, but this problem exists for standard scrolling, too...
