Look inside keysymdef.h for possible symbol names which might produce
desired behavior.  You can notice that it's possible to switch
directly to either first or last group, but not to a specific number.

#define XK_ISO_Group_Shift              0xFF7E  /* Alias for mode_switch */
#define XK_ISO_Group_Latch                              0xFE06
#define XK_ISO_Group_Lock                               0xFE07
#define XK_ISO_Next_Group                               0xFE08
#define XK_ISO_Next_Group_Lock                          0xFE09
#define XK_ISO_Prev_Group                               0xFE0A
#define XK_ISO_Prev_Group_Lock                          0xFE0B
#define XK_ISO_First_Group                              0xFE0C
#define XK_ISO_First_Group_Lock                         0xFE0D
#define XK_ISO_Last_Group                               0xFE0E
#define XK_ISO_Last_Group_Lock                          0xFE0F

The usual group switching symbol is ISO_Next_Group above, but you may
use any other as well (if you use shift_toggle from standard XKB
options, you get ISO_Prev_Group as well).


If this is not sufficient, other programs such as GSwitchIt
(later versions integrated into Gnome 2.6) provide more options, and
do exactly what you call for.
