Made vertical text a section

I took it to the logical conclusion and just made a small section about
vertical text at the end. It makes the document more attractive.

   <p><dfn>Forwards deletion</dfn> deletes text that is logically <em>after</em> the cursor (that is, in the opposite direction to the backspace key). Forwards deletion is often associated with the "delete" key present on some keyboards. (In this article we'll refer to this as "delete" or "deleting".)</p>

+	<h3>Vertical text</h3>
+
+      <p>Vertical text works in a similar way to horizontal text with regard to text selection, cursoring, deletion, and backspacing. As you might suspect, cursor keys on a keyboard in general move the cursor in the direction of the arrow on the key. This usually means that, in vertical text, "up" is generally preceding the current cursor position logically, while "down" is generally following, while "left" and "right" navigate between lines of text.</p>
