Sorry for the stupid question (also I'm not sure it's right thread for it).

But... How to rotate the camera (Editor mode)? I've tried all keyboard keys, checked all toolbar buttons and haven't found anything. In camera Game mode I can easily use in-game keys for the camera rotating, but Game mode has some limits like zoom distance, camera moving speed and so on – which is not comfortable for editing.

Also, it's not very clear how to do some basic things – sometimes I can change a terrain, sometimes I can't and there is no messages/errors/hints for such cases.


Is there any VERY BASIC editor UI description?
