### 3.5 Reference Info

When point is idle for more than `reftex-idle-time` seconds on the argument of a `\ref` macro, the echo area will display some information about the label referenced there. Note that the information is only displayed if the echo area is not occupied by a different message.

RefTeX can also display the label definition corresponding to a `\ref` macro, or all reference locations corresponding to a `\label` macro. See Viewing Cross-References, for more information.
