I think you have the wrong class doc, Kross::ActionCollection doesn't
have such a method addAction taking only 1 qstring parameter. But
KActionCollection does have such a method. And KActionCollection doesn't
do anything with the name except using it in an internal lookup-table
for actions it already know about.

name() is an inherited Qt3 support method from QObject and (IIRC) should
be the same as objectName(). That property is never automatically set,
so you have to set it yourself.

That is because those actions are setup using setObjectName("edit_cut"),
I guess (didn't look up in the source).

No, you just look at the wrong docs. I guess you started at the wrong
point, actionCollection() is a method on KMainWindow (and its
subclasses) not a constructor. And the api for that method would've sent
you to KApplication.
