hi,

im using ym4r to create my maps etc.  
Next to my map i have a vertical list of results. Now i want to make  
that a  
bit more interactive by mouseover over the list to center the map on  
that  
‘marker’.  
i found an example with jquery:

> > but do i really need jquery for that or can i do that somehow with the  
> > tools i already have? (protoype, ym4r, etc)

thx  
tom
