>>25522931Oh come on, don't be ridiculous. OSs provide guidelines, and apps may or may not follow them. Some shortcuts can't be captured, others can.
Not every application quits when hit Ctrl-Q on Windows. Not every application prints with Ctrl-P. Not every application saves with Ctrl-S. Every app dies when you hit Alt-F4.
Not every application quits when you hit Cmd-Q on OS X. Not every application prints with Cmd-P, or saves with Cmd-S (although there aren't many for which this is the case). Command-Option-Escape opens up the Force Quit window regardless of what application is running.
Don't make sweeping generalizations you can't back up.
