How to prevent WordPress from auto creating ol li on list elements?

I found the Answer:

  • I press the Listbutton and get a 1..
  • I write my Text behind 1..
  • I press shift AND enter.

Now I can add everything I want between 1. and 2. without loosing the List-Indent.

Important is the shift key while pressing enter to get to the next line without the next Number.

  • If I want the next Number I press simply the enter button.

This works for Text, Image and Codeblocks from Crayon Syntax Highlighter Plugin.
