If you try to create a keyboard binding for "Alt+Down Arrow" on the Difference Viewer window, the binding is ignored."Alt+Down Arrow" is the default binding for next difference in WinMerge. It is quite handy because the programmer's right hand is already on the arrow keys to rapidly move between files being diffed. While the default binding of F8 is nicely consistent with the rest of Visual Studio, it's just not as fast for multi-file diffing.
