If you can’t see some of the buttons and links described in these tutorials it may be because you’re working on a smaller screen. If that’s the case you may want to take advantage of the collapsible menu in your dashboard.
On the left side of the screen is the main navigation menu detailing each of the administrative functions you can perform. At the bottom of that section is a Collapse menu button that shrinks the menu into a set of icons, or to expands to list them by major function. Within each major function, such as Posts, the sub-menu expands (fly-out) when hovered over, and expands fully if an item clicked.
The large area in the middle of the screen is the work area. It is here the specific information relating to a particular navigation choice, such as adding a new post, is presented and collected.
