I've finally found the wear-marks to be very useful esp. on Search Results. Okay, I was a bit slow learning to really use them. However, I've run into a case where I can't determine what the wear marks are. I was trying to verify the scope of the scroll bar by finding the place of the passage I am current on in the scroll bar. I can't because of the slider. Yet, if I move the slider I change what passage I'm on. (Yes the physics of the viewer affecting what is viewed came to mind.) I would have though that with excellent coordination I could pick up the wear-marks beside the slider but I was unable to do so. Am I supposed to be able to do so? and, if not, why not?
