To place a compound verb form (or its affirmation) in focus, it may be enough to place the main sentence stress (which normally goes on the focused item) on the first component of the verbal compound expression. Here it seems that the auxiliary part of the expression is treated as representing the "verb" in the general focus rule, thereby predictably throwing the focus onto the preceding component, which is now the main verb. In western dialects an alternative procedure used to emphasise the placement of focus on the verb is to make this a complement of the verb "egin" 'do'.
