Test case that can be used to see event.keyCode for various keypresses

When examining the event.keyCode in an onkeypress event handler, the shift key is ignored when the command key is also pressed. For example, here are the keyCode values I get when hitting the following keystrokes:

a - 97
shift a - 65
command a - 97
command shift a - 97

For the last keystroke, I would expect to get a keyCode of 65. The modifiers are correctly set on the event object, but due to different keyboard layouts across the world, it's dangerous to assume, for example, that command 7 results in an ampersand.

This is what the U.S. keyboard layout has in its Cmd+Shift plane. You can verify this by opening the Keyboard panel (which can be enabled via Mac OS X Keyboard preferences pane). Cmd and Cmd+Shift panes both have lowercase letters.

We don't have any information about key presses besides what the OS tell us based on keyboard layout, so there is no practical way for us to change this behavior.
