Open - Click to open pages and files within your site

Open Recent - Shows pages you have recently opened.  Clicking on one will make that the active page.

Close - Closes the page you are working on - a box will open asking if you wish to save changes. This will only open if you have not saved changes.

Close All - Closes all pages you currently have open in SiteBuilder.  The same message will appear as it does for Close The message will appear for each page that has unsaved changes.
Save  - Saves current changes you have made to the page.

Save As - Allows you to save the current page under another name.  It does not eliminate the original page. It copies the content.

Save All - Saves changes to all the pages you have open in SiteBuilder.

Revert to Saved - You make a lot of changes to the page and then decide you don't like it.  Clicking this option, the page will revert back to your last save.

Here you can customize the Error page to match your site.
The Error page comes up if  a page you have deleted or re-named is still in the Search Engine's cache.

Publish -Publishes your page to the Web.  Choosing Publish All will publish all pages you have open in SiteBuilder.
