I would like to establish a sign that indicates unspecified axial movement, i.e., movement that stays in place and does not travel. As far as I know, such a sign has not been standardized. I have been using the indication in Ex. a. It is derived from an action stoke and a spot hold. Ex. b-e illustrate how the sign can be used. I would be interested in knowing what others think of the sign, or if they have a better idea for such an indication.
