When you want to link a user to a specific part of your page you will use  Anchors. For example the Enfold demo has a One Page Portfolio homepage and each section of the page is contained inside Color Section elements (using the Advanced Layout Builder). To point you, the visitor, directly to the portfolio section I would use this link:

http://www.kriesi.at/themes/enfold/homepage/home-v7-one-page-portfolio/#portfolio

Notice the #portfolio at the end? That is the anchor. Adding your own sections with anchors is as easy as adding the anchor name to the Section ID field when editing the Color Section from the Advanced Layout Builder:
