Type the new text in the box. Make sure the text has the Page Title H1 styling. The H1 is very important in order to meet accessilibity compliance. It is also important to be somewhat descriptive with the title for accessibility compliance because page titles should be unique within the site (i.e. - use "Library FAQ" instead of "FAQ").

After saving the page you may notice the name of the page in the left sidebar (the site structure) does not change with the page title.
It is OK for the name in the site structure to be slightly different and/or shorter than what is on the page. However, if you wish to change the name in the navigation (automatic links on parent page) also, you will need to do that on the Form tab.
