### 8.4. Compound structures and decorations

This section presents some commands that produce a variety of medium-sized mathematical structures including decorated symbols and fraction-like objects.

#### 8.4.1. Decorated arrows

The commands \xleftarrow and \xrightarrow produce horizontal relation arrows similar to those used for the commutative diagrams in Section 8.3.4; they are intended to have textual decorations above and/or below the arrow and the length of the arrow is chosen automatically to accommodate the text. These arrows are normally available in only one size. Thus, they will probably not be suited for use in fractions, subscripts, or superscripts, for example.

The textual decorations below and above the arrows are specified in an optional and a mandatory argument to the command.
