You can get the position of the insertion point with  
entry.index('insert'), and set it via entry.icursor(index). If you want to  
do this as the user types, take care to bind to KeyRelease; this way, the  
character corresponding to the key has already been entered in the entry.

BTW, you may also want to automatically select the part that the user  
hasn't actually typed. This can be done with entry.selection_clear(), then  
entry.selection_range(start_position, end_position).
