Actually, there is a way to achieve what you are looking for in Excel. Here are the steps:

1. Double-click on the cell that you want to edit.
2. Place your cursor at the point in the text where you want to move down.
3. Press and hold the Alt key on your keyboard.
4. While holding the Alt key, press the Enter key on your keyboard.

This will move the text down within the same cell without the cursor jumping to the cell below. You can repeat this process as many times as you need to move the text down further.
