[jQuery] Is it possible jQuery do similar actions width $("this") such as selectors like $("DIV A")

[mtest]

Firstly, sorry for my english, but it's very important to me know the
answer :).

For example there is such a code:
<dl>
    <dt>Menu</dt>
    <dd>SubMenu1</dd>
    <dd>SubMenu2</dd>
    <dd>SubMenu3</dd>
</dl>

i call function:
$("dl").bind("mouseover", function(){

I get the object DL, witch now may to call like     this     or     $
(this):

How I can get now DT or DD using    this   ?

I know that can do like     $("DL DT")      or    $("DL DD")?

But now in    $(this)    I have yet selected DL

How can i use     this     with selectors??

$("this DT")  - not right

$(this "DT") - not right

$(this DT) - not right

How????

Please help me :)
