Memento equivalent of SelectSection?

I'm upgrading my script to use memento, but I've come across these two macros:

!insertmacro SelectSection ${blah}

and

!insertmacro UnSelectSection ${blah}

How can I write those two commands using memento? Any help is appreciated.

Those just work the same as without Memento.

I see... I just took another look at the Memento.nsh to learn how it works. Thanks =)
