Other possibilities are enumerated later. +.PP +.I Bzmore +looks in the file +.I /etc/termcap +to determine terminal characteristics, +and to determine the default window size. +On a terminal capable of displaying 24 lines, +the default window size is 22 lines. +Other sequences which may be typed when +.I bzmore +pauses, and their effects, are as follows (\fIi\fP is an optional integer +argument, defaulting to 1) : +.PP +.IP \fIi\|\fP<space> +display +.I i +more lines, (or another screenful if no argument is given) +.PP +.IP ^D +display 11 more lines (a ``scroll''). +If +.I i +is given, then the scroll size is set to \fIi\|\fP. +.PP +.IP d +same as ^D (control-D) +.PP +.IP \fIi\|\fPz +same as typing a space except that \fIi\|\fP, if present, becomes the new +window size.
