Actually, that was the closest thing that I did find to a good list during my initial search! The only reason I didn't stick with it is because I'm pretty sure my coworker's phones have more than those ... if I'm not mistaken, they had one for "drink" or something (it was an image of a beer mug), among other things.
Also, I'm hoping to get a list that includes images, so I can print it all onto a small card to put in my wallet.
But thanks very much for the quick reply; I do appreciate the help!
