In the upper-right corner of the window, click the Settings icon (the small gear graphic) and then, on the menu that appears, click Site Settings.
On the Site Settings page, in the Web Designer Galleries section, click the Site Columns link.
Site columns can be reused throughout a site or any child sites that inherit from the parent site. The site columns that you see within your site might belong to a parent site.
Remember that Site Columns can be inherited from a parent site. This is why you might need to click the Source link to navigate to the parent site if you want to view detail about a particular column. Also, when you click an entry in the Source column, you are taken to the Site Columns page within the parent site, so don’t forget to navigate back after you have finished exploring!
In the Source column, select a site column with a clickable link. If this link is not clickable, you can proceed to step 4.
In the Site Column column, click the name of the site column that you want to view.
After you finish viewing the column information, scroll to the bottom of the screen and click Cancel to return to your previous view.
Make use of any preconfigured site columns whenever possible (including the out-of-the-box columns). You will save time and make your site more consistent.
Inspect the Language and URL site columns. Examine the differences between these two columns.
