Discovered something by accident the other day while editing in Final Cut Pro 4. Had my mouse pointer over a viewer window, and happened to scroll the wheel on my Logitech optical mouse. The clip in the viewer moved! Moving the mouse wheel one click advanced (or reversed) the clip one frame. Worked in the timeline and the canvas as well! Saves the cost of buying a Shuttle Pro unless you need/want the other features it offers. Found that it also will scroll some things sideways if the mouse pointer is on or near a bottom scroll bar. All kinds of fun! Ted Langdell Ted Langdell Creative Broadcast Services Marysville, CA
