How to delete a table of contents?

It sounds like a stupid question, but I cannot delete my table of contents again? I only used the TOC in the draft, but don't need it in the final version of my document anymore. But - it sounds stupid - I cannot delete it. I marked it and hit the delete key, the back key. No more idea of how to delete the TOC. I even found no hint in the manual.
Any tips? Thanks.
