It's probably the same in Lion.
Well you know what happens when you assume don't you? The layout in Lion is not the same as that in Leopard or Snow Leopard. In Lion there are Arrows, Parenthesis, Punctuation, Currency Symbols,Pictographs, Bullets/Stars, Math Symbols, Letterlike Symbols, Emoji, and Latin. If the command symbol is in there, I am unable to find it. Neither can I find a key combination in Keyboard Viewer that will produce the Command symbol.
