To edit the page settings, you can either right click on the page, in the page tree, and choose "Edit" (Img. 2.2.1) or the page properties icon above the page content area (Img. 2.2.2).
The tab "General" contains all the information regarding the page type (1), the page title (2), alternative navigation title (3), if you want the title shown in the menus to be other than page title, the speaking URL path segment (4), to alter the URL of the page, and finally the option to exclude the page from the URL (5). (Img. 2.2.3)
Below the tab "Access" you have the visibility option, to disable the page (1) and hide the page from the menu (2). It is also possible to set publishing (3) and expiration (4) dates of a page here. This setting can be set to include all subpages as well (5). (Img. 2.2.4)
The tab "Appearance" contains template selection for the page, which means the layout of the page. All available templates can be found in the dropdown or by selecting through the thumbnails (1). It is also possible to set what template should be used for all subpages of this page (2).
In the case where you wish to have the same page content available on more than one page, but not having to edit it on multiple places, you can use the function "Show content from page". One field shows what page the content is fetched from (3) and there is a search field (4) to search and add page. (Img. 2.2.6).
Below the tab "Behaviour" you can find functions like Link target (1), which is used to force a linked page to open in a new window. This is mostly used when creating a page that links to an external URL. If you wish to exclude a page from being cached, you can disable the function (2). If you wish to exclude a page from the internal search function, on your website, this can also be selected (3). (Img. 2.2.7)
