Using Fitaly Stamp with Brainforest

I'm using Fitaly Stamp with Brainforest (an outliner) and am stumped one set of Graffiti strokes I need:

To move items up in the outline, it says to use the Graffiti stroke for "previous field". This is an up-and-down stroke. Similarly, to move items down, I need the "next field" Graffiti stroke.

Any clues on how to translate Fitaly to these Graffiti strokes?
