The Admin Bar on the WordPress Dashboard
The admin bar is the menu you see at the top of the WordPress Dashboard. The admin bar appears at the top of every page on your site, by default, and across the top of every page of the Dashboard if you set it to do so in your profile settings.
The nice thing is that the only person who can see the admin bar is you because it displays only for the user who is logged in. The admin bar contains shortcuts that take you to the most frequently viewed areas of your WordPress Dashboard, from left to right:
The name of your website: Go to the front page of your website.
Comments page: The next link is a comment balloon icon; click that and visit the Comments page on your Dashboard.
New: Hover your mouse and you find links to Post and Page, which you click to go to either the Add New Post page or the Add New Page screen. You can also navigate to the Media Library or the Users page on the Dashboard.
Your photo and name display: Hover your mouse pointer over this to open a drop-down menu that provides you with links to two areas on your Dashboard: Edit Your Profile, and Log Out.
Again, the admin bar is seen only by you at the top of your site, no matter what page you’re on, as long as you are logged in to your WordPress site.
