Manual 'Trail' button.

It would be nice to have two directional buttons that will move my stop up or down a certain number of ticks when clicked. The user should probably(?) be able to adjust the stop placement in either direction independent of being long/short. The number of ticks to move the stop would be the same for each direction, but it would be great if users could set this value. It would be even better if it can be set by instrument (ie, for ES vs GC ticks per point).
