Smart guides (some users call them whiskers) are guides that are not visible on the slide all the time. In fact they only make an appearance when you start moving slide objects around. Move any slide object and these guides show up dynamically — that’s how they ended up being called “dynamic guides”. Whatever you call them: smart guides, dynamic guides, or whiskers — they are of great help when you align slide objects. These guides work like little alignment lines that appear when you drag one object close to another.
