Nope, sorry, it's for phones and is a "helper" for when the Floating Action Button is enabled.
In the "grand design news" category:
The latest update of Google Keep does not, I repeat does not, use the Floating Action Button.
Instead it has an icon bar along the bottom. I repeat, along the bottom.
And as we all know, "icon bar along the bottom is not part of Material Design". What has the world come to?
