ShiftL + u = U ShiflR + u = 7 thansk for help [1] Which of the actions bound to a given key is taken when it is pressed depends on what modifiers are in effect at that moment. The keyboard driver supports 9 modifiers. These modifiers are labeled (completely arbitrarily) Shift, AltGr, Control, Alt, ShiftL, ShiftR, CtrlL, CtrlR and CapsShift. Each of these modifiers has an associated weight of power of two according to the following table: modifier weight Shift 1 AltGr 2 Control 4 Alt 8 ShiftL 16 ShiftR 32 CtrlL 64 CtrlR 128 CapsShift 256 -- Xiangfu Liu Email: xiangfu at qi-hardware dot com Web: http://www.qi-hardware.com -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
