I grab the string and/or some beads I don’t want to move together between my thumb and finger on one hand, and push the bead I do want to move with my thumb and finger of the other hand. (I don’t need to see it because I can feel it and the beads don’t move with my touching it.) I can also do it more awkwardly with one hand.
