Console

Up in the View Menu other windows you will see one called "Console".

This is where you would enter console commands that allow the toolset to interact with the game engine. It is mostly (if not always) used when you have an area open in the Area Editor.

The console commands were built to work with the game not the toolset but some of them do work with the toolset alone.

Your toolset will crash when using some of them so make sure you save your work before trying them.
