As I mentioned, less might not be quite what you are looking for. -z does
not set the window size, it sets the scrolling rate. This value applies
to commands like ^B and ^F not to filling the first screen.

If you do:

mode co80,15

then you will get a 15 line display. An alternative, which I mentioned
before, is to use:

head -15

but that's only going to slow the first 15 lines.

>The less --help screen says "Commands marked with * may be preceded by a
>number, N" but apparently that's wrong because specifying -15z gives an

True. You are misreading the help. Commands are commands. Option
switches are option switches.

>I also tried -y15 ("maximum forward scroll") but that doesn't work either
>(it scrolls a full screen of lines just like -z15).

You need to read the man page. -y does not mean what you appear to assume
it means.

-z does control the scroll rate. There's something wrong with how you are
testing this. Fill your test file with line numbers so you can see how
much movement there really is.

Regards,

Steven
