The help() function uses (by default, on Windows) the built-in
"more.com" command. There's some hand-waving going on there because it
can/will be overridden if you have a different "more" executable
available before the system-provided more.com or if you have a PAGER env
If you, at the Windows command prompt (ie *not* in Python), type:
You can see the various keystrokes which the program responds to.
Specifically, the last two lines show:
<space> Display next page
<ret> Display next line
which is, I suspect, what you're after here.
(If you're interested, the code for all this is in the pydoc module
(Lib\pydoc.py) in the getpager() function.
