I'll help you complete this task. Let me start by taking a screenshot to see the current state of the webpage.

Good! I can see a text editor webpage with a text area and a "Clear Editor" button. The cursor is visible in the text area. Now I'll complete the task step by step.
**Step 1: Type the text with line breaks**
I'll click in the text area first to ensure it's focused, then type the text. The text should be: "Line one\nLine two\nLine three\nLine four"

Good, the text area is now focused (I can see the blue border around it). Now I'll type the text. I need to type "Line one", then press Enter for a new line, then "Line two", Enter, "Line three", Enter, and "Line four".

Perfect! "Line one" has been typed. Now I'll press Enter to create a new line and continue with "Line two".
