Keyboard Shortcut
When an item is selected in the folder (left) frame of Windows Explorer, CTRL+UPARROW and CTRL+DOWNARROW scrolls the folder frame window up and down (just like moving the scroll bar). The selection doesn't change. Note that the folder (left) frame must be scrollable (it must have a scroll bar which means it has more items than the frame can display at one time) for this to work.
