Gary was trying to use the ctrl + ↓ keyboard shortcut to scroll without moving the text cursor. ctrl + ↑ works as intended to scroll, but he's lost the ctrl + ↓ functionality. He is having the issue on multiple laptops. It appears Apple removed or started overriding this shortcut at some point.
My colleague Corey who is working with Gary on this found this:
You can add these lines to your Emacs configuration file, which is usually ~/.emacs or ~/.emacs.d/init.el. After adding these lines, restart Emacs or evaluate the changes with M-x eval-buffer. Then, you should be able to use Ctrl + Up and Ctrl + Down to scroll through text without moving the cursor:
;; Map Ctrl + Up and Ctrl + Down to scroll without moving cursor
(global-set-key (kbd "C-") 'scroll-down-line)
(global-set-key (kbd "C-") 'scroll-up-line)
However, Gary told him he shouldn't edit init.el since it might mess with your custom settings. Corey tried adding the above commands in ~/.emacs/custom, but that didn't work.
