Frame Isolator

if you want to tinker with it, or try it, copy it from this box

javascript:f=frames;for(i=0;i<f.length;i++){l=f[i].location;if(confirm(f[i].name+' ['+i+'/'+(f.length-1)+']<br>'+l)){prompt(l);location=l;break}}

or download bookmark to vmu

you can try it out here
when you run this script, it will show you each frame's url one by one... click 'cancel' until you see the frame you want, then click 'ok'... you will see the url in a box that you can alter... click on 'ok' again... it will then show only that frame...

another amazing bookmarklet...
but, of course, it does not work as a bookmark...
