The ‘Tools’ button in the WordPress dashboard gives options for quickly sharing information from your web browser, importing content from other sites (WordPress or otherwise), and exporting the content on your site–as a backup or for moving to another site.
‘Press This’ is a bookmark that you can add to your browser as a quick way of making posts out of content you come across on other sites. When you click on the ‘Press This’ link it creates a post with the title pre-filled for you and a link to the page you are visiting in the body of your post. You can add your own information, edit and change the content and publish the post immediately or just save it as a draft for future use.
The ‘Import’ screen provides a list of tools for importing posts or comments from sites using WordPress and other systems. To help keep WordPress running quickly these tools should be installed as needed. To install one of the import tools, click on the name of the tool you would like to install.
The ‘Export’ feature is a tool for exporting the posts or pages on your site individually or to back up your entire database–including posts, pages, comments, custom fields, terms, navigation menus and custom posts. The ‘Download Export File’ button will create an XML file you can save as a content backup or to move the content from your existing site to a new site.
