I've remapped the laptop key fn to Hyper using:
(setq ns-function-modifier 'hyper)
to scroll other window I set
(global-set-key (kbd "H-n") 'scroll-other-window) (global-set-key (kbd "H-p" ) 'scroll-other-window-down)
H-n works but H-p inserts a * char instead of scrolling down.
M-x scroll-other-window-down works fine, only the mapping does not.
