Some programs have been designed for large resolutions, making life difficult for people with small monitors or compact laptops. The most common problem is when the configuration window is too large to fit the screen making it impossible to reach th "OK" button.
The solution is simple: to shift the view to the missing part of the window by "shifting" the desktop in the needed direction. It could be done with simple key combination like Ctr+Arrows. Note, it is not supposed to enlarge the desktop making it scrolable (wich is very unconfortable), but to simply temporeraly shift it.
I would like to propose this idea for the Gnome and possible KDE projects.
