How do you target a frame panel from a Navigator?

Assuming your web page has a frame defined with:

<FRAMESET COLS="15%,85%">
<FRAME SRC="/db.nsf/Nav1?OpenNavigator" 
MARGINHEIGHT=0 MARGINWIDTH=0 SCROLLING=NO NAME="top">
<FRAME SRC="/db.nsf/By+Category?OpenView"
MARGINHEIGHT=0 MARGINWIDTH=0 SCROLLING=YES NAME="bottom">
</FRAMESET>
<NOFRAME>
You need a browser that supports frames.
</NOFRAME>

Name your navigator:

Nav1  | Nav1
