==== Terminology ====
The tool that lets you visually select an element on that page for use by "element-centric" tools (such as the Style Inspector) is called the Highlighter. It has a menu item on the Mac at Tools->Web Developer->Highlighter and on Windows at Firefox->Web Developer->Highlighter. You can also get to it via a "Highlight Element" context menu item.
The Highlighter has two modes:
* Highlight mode – as you move the mouse around, the highlight follows until you click a page element
* Selected mode – an element is selected and you can freely move the mouse around without changing the selection
The Highlighter Toolbar has a button, labeled "Highlight" that switches between the Highlight and Selected modes.
