Finally I the "ultimative" proof: When using Jasspa's Micoremacs and pressing Alt-Ctrl-RMB, Microemacs reports: ey not bound "A-C-mouse-pick-3" (when pressed) Key not bound "A-C-mouse-drop-3" (when released) which means: There is no keybinding (inside Microemacs) found for ALT-CTL-RMB.... So, how should I further handle this case ? :O) Meino
