# X coordinate to output a MoveToScreen command that will move a
# window to the left or right screen.  If already on the left-most
# screen, it will be moved to the furthest right screen.
#
# Requires that you are running your multiple displays as one giant
# desktop (ie: Xinerama).  This will not move windows between 2
# independent X displays.
