       Actions associated with the XkbGroupAction structure change the current group state when keys are pressed
       and released:

           typedef struct _XkbGroupAction {
               unsigned char    type;       /* XkbSA_{Set|Latch|Lock}Group */
               unsigned char    flags;      /* with type, controls the effect on groups */
               char             group_XXX;  /* represents a group index or delta */
           } XkbGroupAction;

voidXkbSASetGroup(XkbActionact,intgrp);
