I think Eli suggested specifically in some previous email to bind C-x 4 h to
help-mode-map, so that all help-mode commands are available as 5 or 6 keys
combinations, like C-x 4 h s for view-source.

I don't think scroll command is implemented as help specific commands; you have
end/beginning of the buffer, next/previous page, as well as next/previous link
(button). Do you really need scroll command too? I mean we mostly just read
help.

When it comes to some potential general key for doing stuff in "other-window"
via pre/post hook, only one is needed, since it will do stuff in any
"other-window" not just help or info; however, some windows are usually *not*
other-window, or very seldom, like those special buffers. With a "remote"
control like wrapping their commands in with-seleceted-window and putting their
mode-map on a prefix-key, which becomes a "buffer remote control", those special
buffers can be excluded from "other-window" consideration totally, so they are
never considered the "other-window" at all. If it is useful or not, I guess is a
personal preference.
