Also pay attention to what pre-highlights before you select it and read what is says in the little pop-up info box.
As Stephen said, by activating a tool first you will have preference to select that type of element first (must use SHIFT key of course to select).
When you have overlapping elements watch the info box and use the TAB key to cycle through all the available possible selections.
