Check Out. The Check Out option locks a file for editing by a single user. If other users attempt to save back to the file, they'll be notified that they can't make changes until the user who has the file checked out currently checks it back in and makes it available for editing.
Checking out a file locks it for editing by a single person.
Version History. This option opens the Version History window and shows you all the versions of the document that SharePoint knows about, including the number, the date and time of the version, who uploaded a particular version, how big the file is and any free-form comments that were included by the user at the time of the upload. (You can't edit previous comments; you can only add new comments to new document versions.) This creates a user-friendly audit trail that can help you track down inadvertent or incorrect modifications and back up to a good version if someone makes a catastrophic mistake.
Alert Me. This helps you set up alerts for this particular item. We'll talk more about Alerts in the "5 tips" piece of this cheat sheet.
You can see the version history of any file.
Send To. On this menu, you can move a document to another library on the SharePoint site, or you can email a link to this document library to someone else. You can also download an independent copy of this document to use locally on your own PC, although choosing this option doesn't keep the copy of the document on the SharePoint site updated. You can also create a new document workspace -- a SharePoint subsite -- with this document preloaded in case more focused collaboration is necessary, for a subcommittee, for instance.
Deleting a file from the library.
Delete. This simply deletes the file, after a confirmation prompt, from the document library. A copy is stored in the site's Recycle Bin (accessible by default, unless the administrator has turned this feature off, in the left Quick Launch bar at the very bottom of the menu) in case you delete something by mistake. (If the Recycle Bin appears, it's enabled; if you don't see it, it's not enabled; you can't use it if you can't see it.)
Customizing the document library
SharePoint 2010 lets you use the Library Tools Ribbon to manage and further interact with documents in your libraries. In some cases these are actions you can perform in other ways (as described above); this just gives you a different way in. For instance, on the Document tab, you can perform operations grouped as follows:
