When more than a page of text is output to the user it is controlled by a ``pager''. This allows the user to move easily backwards and forwards through the text as well as allowing some more powerful options such as keyword searching.
The text is output a number of lines at the time. f or 
RETURN
gives the
next set of lines, b may be used to get the previous
set of lines, s goes to the start of the text,
q to quit the text, and a line number followed by RETURN may be
typed to go immediately to a required line number in the text.
? or h gives a list of the available commands, which are all a single letter or a number. The letters may be entered in upper or lower case. n allows the number of lines in a ``page'' to be user set.
Keywords may be searched for with the > and < commands, for forwards and backwards searching respectively. The searching is ``auto-wrapping'' i.e. if a keyword is not found at by the end of the text (forwards search) the search is carried on from the beginning of the text. The user is prompted for repeat searching. By default the searching is insensitive to letter case. This behaviour may be toggled on and off using the command c.
