How do I erase a large area of a tilemap inside the editor ?

Hi.

I would like to erase a lot of tiles in the editor. There is a rectangle tile editor but I think it can be only used to draw tiles, not to erase them.

Any quick way to do this ?

Rectangle Select+Delete

Thank you.

or click right mouse button

Well, neither of your instructions work for me. What could I do wrong ?

edit : nevermind, found it.
