I don't get it. How can I tell which function from a menu I've executed? 
It's not like the menu changes afterwards... If I don't use access key 
but navigate through it via the cursor keys, I select the entry, hit 
enter and it is executed. Exactly the same goes for for a split menu 
button: I open the menu, select the entry, hit enter and it's executed.

I've been using split menu buttons in several applications for years 
without them feeling weird at all. The only thing that feels weird is 
delayed menus, but we all agree we want to get rid of those, right?
