That's right, you shouldn't "use the visual properties as multi-modal 
ones", you should think about what the visual property is supposed to 
express and develop that into a multi-modal cue.  Popup windows are a good 
example of a visual cue that can't be represented multi-modally (for some 
properties that can, see 
http://www.physics.mcgill.ca/WWW/seibert/style/mms.html).

The underlying idea of a popup is that the new window is spatially 
separated from the old, but the old window is still present.  Separating 
the windows so that both can be viewed simultaneously works well for 
visual browsers, but can't be done with a simple audio browser because 
you only have one dimension (time) to work with.  Perhaps you could do it 
in a sophisticated browser with spatial audio resolution (see 
http://www.physics.mcgill.ca/WWW/seibert/style/raman.html), but then the 
listener would have to follow two tracks at once rather than skipping 
back and forth, which he could do just as easily without having a popup 
feature.  The easiest way to deal with a popup window for non-visual 
browsers is to just make it into a standard hyperlink.
