CTRL + SHIFT + F should be show in the debug section.

should make a reference to CTRL + SHIFT + F, it is the first place where people will look for it.

It is one of the most useful tools for debugging the game offers and it is not display there.

I always get lost trying to find the key for showing the object data.

Yes, it shows in control, but that is the last place one will look for a debug information.
