so in awesome they have that code (key.c):

    if(state & globalconf.modeswitchmask)
        k0 = xcb_key_symbols_get_keysym(globalconf.keysyms, detail, 4);
        k1 = xcb_key_symbols_get_keysym(globalconf.keysyms, detail, 5);
        k0 = xcb_key_symbols_get_keysym(globalconf.keysyms, detail, 0);
        k1 = xcb_key_symbols_get_keysym(globalconf.keysyms, detail, 1);

http://cgit.freedesktop.org/xcb/util/tree/keysyms/keysyms.c and in here
i found the following text:

	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 // which group ?
	as if the first element were the lowercase form of ``K'' and the second // i thought second is XCB_NO_SYMBOL ?
	element were the uppercase form of ``K.''

so why do they use 4 and 5 as param and not 3 and 4?
