When running the Clusterize pseudo-plugin,
and when the Rpt table is open, if you press the 'j' key while the input focus goes to an image viewer window, then the crosshairs will jump to the location of the peak (or cmass) of the cluster in which the clusters currently reside. The purpose of this is to let you get to that location once you click in a blob, without having to switch your gaze from looking at the image to find the right 'Jump' button the the Clusterize Rpt table.
Similarly, the 'f' key will flash the current cluster.
If the crosshairs are not inside a cluster, then the terminal should beep at you, and nothing else exciting will transpire.
These features are for Dale, but others may find them useful.
