standard objects and primitives

[Nala1977]

Hey guys, might be a stupid question, i've checked the wiki, but there is no info about it.

you can add objects like rock sphere cube plane etc, but how do you displace or modify them? they only come with an output and they do not accept any input node.
a bit confused

You have to work inside (+) or relink something outside to the internal input, then it'll switch to an outside input. If you get my point.
