How to control which tiny editor is used in editable block

[InfGame]

Just a question because i dont seem to really understand how to control it.

I have a template where there are some blocks i only want users to change if the text is bold/ italic or normal (the small editor type)

and then there is others where i want them to have more freedom with append links to words and such (the normal editor?)

and ther eis also a 3rd type of editor which i cant seem to get to where you are also able to paste variables into the textblock.

my question is how do i control which type of tiny editor is used.
