question about "itemize"

[Tom Goldring]

Suppose I have an itemized list like

    paragraph 1

       - paragraph 2

    paragraph 3

where paragraph 2 is nested. If I enter this by choosing the "itemize" 
environment, then typing

paragraph 1 <return> <tab> paragraph 2 <return> <shift-tab> paragraph 3

LyX creates paragraph 3 as a new item. Is there a way to have paragraph 
3 not be a new item? For example, if I enter paragraph 3 in the "Quote" 
environment, it will look like I want it to on the left (i.e. it will 
have the same indentation as paragraph 1 without the large dot that 
indicates a new item) but if it's a long paragraph it will also be 
indented on the right, which I don't want. In other words, I would like 
it to have the same indentation (both right and left) as if paragraph 3 
were a new item, but without the dot preceding paragraph 3. Hope this 
makes sense.
