Splits and Joins

Users indicate the end of a paragraph to a word processor by pressing the Enter key. Vex has no built-in concept of paragraphs; instead, this behaviour is simulated by using a split . When you press the Enter key, Vex attempts to make two copies of the current element, splitting the element content between the two. Pressing Enter at the end of a paragraph results in a new, empty paragraph, just as in a word processor.

A related concept is a join, 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 Backspace or Delete.
