In what way are PC keyboards necessarily limited to 3 levels? I can easily construct a PC keyboard layout using MSKLC in which characters are assigned to Shift+AltGr keystrokes. In fact, the standard US-International keyboard comes like this. Why does a 3-shift-state keyboard count as 1 group of 3 levels, but a 4-shift-state keyboard counts as 2 groups of 2 levels? What is the difference, other than the fact that ISO 9995 says there can only be 3 levels? -Doug Ewell Fullerton, California http://users.adelphia.net/~dewell/
