The list is intended +to convey the set of symbols on the corresponding key. If the list +(ignoring trailing NoSymbol entries) is a single KeySym ``K'', then the +list is treated as if it were the list ``K NoSymbol K NoSymbol''. If the +list (ignoring trailing NoSymbol entries) is a pair of KeySyms ``K1 +K2'', then the list is treated as if it were the list ``K1 K2 K1 K2''. +If the list (ignoring trailing NoSymbol entries) is a triple of KeySyms +``K1 K2 K3'', then the list is treated as if it were the list ``K1 K2 K3 +NoSymbol''. When an explicit ``void'' element is desired in the list, +the value VoidSymbol can be used. + +The first four elements of the list are split into two groups of +KeySyms. Group 1 contains the first and second KeySyms; Group 2 contains +the third and fourth KeySyms. Within each group, if the second element +of the group is NoSymbol , then the group should be treated as if the +second element were the same as the first element, except when the first +element is an alphabetic KeySym ``K'' for which both lowercase and +uppercase forms are defined. In that case, the group should be treated +as if the first element were the lowercase form of ``K'' and the second +element were the uppercase form of ``K.'' + +The standard rules for obtaining a KeySym from a KeyPress event make use +of only the Group 1 and Group 2 KeySyms; no interpretation of other +KeySyms in the list is given. Which group to use is determined by the +modifier state. Switching between groups is controlled by the KeySym +named MODE SWITCH, by attaching that KeySym to some KeyCode and +attaching that KeyCode to any one of the modifiers Mod1 through Mod5. +This modifier is called the group modifier. For any KeyCode, Group 1 is +used when the group modifier is off, and Group 2 is used when the group +modifier is on. + +The Lock modifier is interpreted as CapsLock when the KeySym named +XK_Caps_Lock is attached to some KeyCode and that KeyCode is attached to +the Lock modifier. The Lock modifier is interpreted as ShiftLock when +the KeySym named XK_Shift_Lock is attached to some KeyCode and that +KeyCode is attached to the Lock modifier. If the Lock modifier could be +interpreted as both CapsLock and ShiftLock, the CapsLock interpretation +is used. + +The operation of keypad keys is controlled by the KeySym named +XK_Num_Lock, by attaching that KeySym to some KeyCode and attaching that +KeyCode to any one of the modifiers Mod1 through Mod5 . This modifier is +called the numlock modifier. The standard KeySyms with the prefix +``XK_KP_'' in their name are called keypad KeySyms; these are KeySyms +with numeric value in the hexadecimal range 0xFF80 to 0xFFBD inclusive. +In addition, vendor-specific KeySyms in the hexadecimal range 0x11000000 +to 0x1100FFFF are also keypad KeySyms. + +Within a group, the choice of KeySym is determined by applying the first +rule that is satisfied from the following list: + +* The numlock modifier is on and the second KeySym is a keypad KeySym. In + this case, if the Shift modifier is on, or if the Lock modifier is on + and is interpreted as ShiftLock, then the first KeySym is used, + otherwise the second KeySym is used. + +* The Shift and Lock modifiers are both off. In this case, the first + KeySym is used. + +* The Shift modifier is off, and the Lock modifier is on and is + interpreted as CapsLock. In this case, the first KeySym is used, but + if that KeySym is lowercase alphabetic, then the corresponding + uppercase KeySym is used instead. + +* The Shift modifier is on, and the Lock modifier is on and is + interpreted as CapsLock. In this case, the second KeySym is used, but + if that KeySym is lowercase alphabetic, then the corresponding + uppercase KeySym is used instead. + +* The Shift modifier is on, or the Lock modifier is on and is + interpreted as ShiftLock, or both.
