Well, pressing SHIFT+ Enter is a pretty standard way of creating what is called a "soft carriage return" in most word processors and also HTML editors (e.g. Dreamweaver). Below is the HTML code, followed by the WYSIWIG result. The <br /> tag is created by SHIFT+RETURN.
<p>this is a one-line paragraph</p>
<p>this is a new one-line paragraph</p>
<p>this is another line <br />
immediately followed by yet another line
</p>
this is a one-line paragraph
this is a new one-line paragraph
this is another line
immediately followed by yet another line
<ul> <li>this is line 1 in a bullet list </li> <li>this is line 2 in the same list </li> </ul>
- this is line 1 in a bullet list
- this is line 2 in the same list
<ul style="list-style:none"> <li>this is line 1 in a non-bullet list</li> <li>this is line 2 in the same list </li> </ul>
- this is line 1 in a non-bullet list
- this is line 2 in the same list
Hope that helps,
