6615 | 21 ## Display documentation for the function @var{function_name} |

23 ## the printed manual, using the GNU Info browser. If invoked without | |
24 ## any arguments, the manual is shown from the beginning. | |

26 ## For example, the command @kbd{doc rand} starts the GNU Info browser | |
27 ## at this node in the on-line version of the manual. | |
28 ## | |
29 ## Once the GNU Info browser is running, help for using it is available | |
30 ## using the command @kbd{C-h}. | |
