But scrolling commands are not specific to Help buffers. For example, scrolling commands that I miss the most to scroll another window are 'scroll-up-line' and 'scroll-down-line' (and 'recenter-other-window' was added recently with an awkward keybinding 'M-C-S-l' for the lack of better variants). It would be unfortunate to add such wrappers 'scroll-down-line-other-window' and 'scroll-up-line-other-window' that can't be bound to a keybinding by default. However, for Help buffers the situation is slightly better since we can bind Help-specific wrappers in the Help keymap, e.g.: 'C-h 4 s' to run 'help-view-source' in the Help buffer. 'C-h 4 i' to run 'help-goto-info' in the Help buffer. These commands could use 'other-help-window' returning the most recently displayed Help window buffer.
