Set Nudge Value to 1/2 Triplet (1/3)

Sets the Nudge Value to one half of a triplet. By my reckoning that would be the full value of one of the notes — quarter note triplet — one half is a full quarter note. I’m not sure that I understand when I might want to nudge things like this, unless I was moving something that wasn’t an actual part of the triplet. Hmmm.

You can nudge regions (move them in small increments) left or right using key commands. To nudge regions, you first set the nudge value, then move selected regions by this value. Alternatively, you can nudge regions by a set value.
