Accidentally deleted “Save Draft” and “Preview” buttons!

While drafting a post today, I accidentally highlighted and dragged the “Save Draft” and “Preview” buttons somewhere…and they completely disappeared! (The “Publish” button is still there.) I can’t find them anywhere on the Edit Post page to use or drag back to their proper place.

After reading other posts, I’ve already tried (to no avail):
– Looking for the buttons at the bottom of the “Edit Post” page
– Using three different browsers to try to locate the buttons
– Deactivating all plugins
– Playing with the checked boxes in the “Screen Options” dropdown
– Making sure my page was set to 2 columns, not 1

And I still can’t find these buttons! Please help!
