I am a semi-recent Mac user (not a switcher, but a cross-platform user), and I have had the hardest time learning the special symbols for the OS X keys (shift, control, option (alt), command (open Apple)). I made this widget as a personal reference and thought I would share it with the world.
I must admit that through the process of making the widget, I have pretty much learned the symbols and what keys they match to now.
