It seems these fundamental issues can't be fixed without changing core functions. The problem is that another window's buffer should be selected before reading a key sequence in it and executing the bound command. So the only reliable alternative is to have global keymaps with tons of commands that use with-selected-window. To make them at least more general that just Help/Info specific, a better pattern would be to base these commands on 'scroll-other-window', e.g. (defun forward-char-other-window (&optional n) (interactive "P") (with-selected-window (other-window-for-scrolling) (forward-char n))) (defun backward-char-other-window (&optional n) (interactive "P") (with-selected-window (other-window-for-scrolling) (backward-char n))) (defun forward-word-other-window (&optional n) (interactive "P") (with-selected-window (other-window-for-scrolling) (forward-word n))) (defun backward-word-other-window (&optional n) (interactive "P") (with-selected-window (other-window-for-scrolling) (backward-word n))) ...
