:write-quit-all

Aliases: :wqa, :xa

Writes (saves) all unsaved buffers to disk, then closes all views, exiting the editor. Scratch buffers (without associated paths) will not be saved, and exiting the editor will fail if there are any such buffers open. Identical to :write-all followed by :quit-all.
