Users could control placement of text by means of: margins; indentation; normal tab stops; decimal tab stops, which set the position of the decimal point rather than the start of a number; and left, right or full justification. Different combinations of these settings, called "layouts", were automatically numbered, which made it possible to re-use layouts and to make changes that applied to all parts of a document where a specified layout was used. These facilities could be used for presenting tables.
