This tutorial shows how to manage the Primary links menu in Drupal 7 templates.
You can see the Primary links menu on the screenshot below.
Go to Structure – Menus. You will see several menus. We need the Main menu. Click on list links in order to access the menu links.
We can see the menu links and sub menus. You can re-order the menu items, change titles of menu links, disable and delete them. Click on edit.
Change the menu link title and save the changes. Please note that the Path cannot be changed. You will need to create a new link and assign a path to it.
Uncheck the box in case you want to disable the item. Drag the menu link in order to change its position. Click on Add link in order to add a link to menu.
Save the changes and check your site.
