By experimenting, I found that the Ctrl-Alt combination does the same on Windows. I also discovered another undocumented feature: by holding down Ctrl and dragging you can digitise your freehand curve tracing or other doodling. After selecting, a Ctrl-C is always needed to copy the list of coordinate pairs to the clipboard. John Jowett
