Looks like the command is run, but I swear it wasn't by me, at least not intentionally: Debugger entered--entering a function: * scroll-lock-mode(toggle) funcall-interactively(scroll-lock-mode toggle) call-interactively(scroll-lock-mode nil nil) command-execute(scroll-lock-mode) The command is bound to Scroll_lock. But that is not a key on my keyboard, nor one I press intentionally. What I did to get that stack trace was to Alt-TAB to a different window and back. Could it be that Alt-TAB is interpreted as Scroll_lock?
