| <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> |
