Firebug does this much better. You click on a special "inspect" button and firebug enters a select-element-mode so you can select the element you want. When you move the mouse over the different elements on screen they are highlighted with a border. As soon as you click somewhere you leave that mode and the web page behaves as normal and the element shows up in firebug. Right now with the web inspector I have to disable any dhtml menus to be able to inspect anything and it is impossible to inspect the elements that make up the menus. I suggest the web inspector should behave like Firebug in this case.
