http://unix.stackexchange.com – Is it possible to have multiple applications associated with a specific file type that and controlled via modifier keys? For example for avi video files we be able to assign both VLC (default) and mplayer (alternative) and normally it open these files using VLC as default and when we hold modifier keys (Ctrl,Shift,Alt) it open file with second third ,... alternative application. Is it possible? How? Thanks (HowTos)
