Best on a phone or tablet, with four fingers on the screen.

With a mouse, each drag is one finger:
· start above the line for a hand, below it for a foot (left half is your left side)
· let go of the button and that hand or foot keeps holding
· drag again from the same area to move it to a new hold
· right-click in its area to let go, or Backspace to let go of everything
· to jump, let go of everything, then double-click a hold
