<h1>Splits and Joins</h1>
<p>Users indicate the end of a paragraph to a word processor by
pressing the <b>Enter</b> key. Vex has no built-in concept of
paragraphs; instead, this behaviour is simulated by using a <i>split
</i>. When you press the <b>Enter</b> key, Vex attempts to make two
copies of the current element, splitting the element content
between the two. Pressing <b>Enter</b> at the end of a paragraph
results in a new, empty paragraph, just as in a word processor.</p>
<p>A related concept is a <i>join</i>, where two elements of the
same type are joined together into one. You join two elements (such
as two paragraphs) by placing the caret near the boundary of the
elements and pressing <b>Backspace</b> or <b>Delete</b>.</p>
