Shift+up/down arrow keys works like in Explorer, but Ctrl+up/down arrow keys moves highlighted files up/down! Instead this should be assigned to something like Alt+up/down arrow keys, since it is an alternate action, not the normal one. The normal action everyone is used to is that Ctrl+up/down arrow keys moves the selection rectangle up/down, and then Spacebar can be pressed when required to select/deselect files. So in JD also Shift+up/down arrow keys should work the same standard way, and a selection rectangle should be displayed. Moving file links should be assigned to Alt+up/down arrow keys.
