Hopefully documentation can be added on how to interact with the toolbar.

Issue description:

Godot has some useful tools for making small helper tools, such as point. But I can't find any documentation on how to interact with them, like calling them/listening to their signals/etc.
If there was documentation on these, I think they could be very useful sometimes.
