Other possibilities are enumerated later. +.PP +.I Zmore +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. +To use a pager other than the default +.IR more , +set environment variable PAGER to the name of the desired program, such as +.IR less . +.PP +Other sequences which may be typed when +.I zmore +pauses, and their effects, are as follows (\fIi\fP is an optional integer +argument, defaulting to 1) : +.PP +.IP \fIi\^\fP +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. +.PP +.IP \fIi\^\fPs +skip \fIi\fP lines and print a screenful of lines +.PP +.IP \fIi\^\fPf +skip \fIi\fP screenfuls and print a screenful of lines +.PP +.IP "q or Q" +Quit. +.PP +.IP = +Display the current line number. +.PP +.IP \fIi\fP/expr +search for the \fIi\^\fP-th occurrence of the regular expression \fIexpr.\fP +The user's erase and kill characters may be used to edit the regular +expression. +Erasing back past the first column cancels the search command. +.PP +.IP \fIi\^\fPn +search for the \fIi\^\fP-th occurrence of the last regular expression entered. +.PP +.IP !command +invoke a shell with \fIcommand\fP. +The character `!' in "command" is replaced with the +previous shell command.
