Looking at the keyboard shortcuts, I do not see one for 'move transition up' or 'move transition down'.
So there are 10 transitions and I add a new on. Instead of right clicking and selecting 'move transition up', it would be nice to do something like control up to move it up a spot.
control-up (move up 1 spot)
control-down (move down 1 spot)
control-home (move to first spot)
control-end (move to last spot)
