In the case of movies or simulation trajectories, it is often useful to quickly jump between different frames but not necessarily in any order. This script allows the user to specify a list of frames and flipping through the set of frames is controlled by a user-defined keystroke (limited to those available through the Set Key command). This script is a nice tool for identifying different protein states from a simulation and can be used in conjunction with the Modevectors script in a very useful way by first characterizing the directionality of the movements (using Modevectors) and then visualizing the change directly using this script.
