RET (translated from <return>) runs the command magit-diff-visit-file (found in winner-mode-map), which is an interactive compiled Lisp function in ‘~/Documents/dotfiles/conf/emacs/.emacs.d/elpa/26.3/develop/magit-20190906.2217/magit-diff.el’. Its keys are remapped to ‘magit-diff-visit-file-other-window’. Without this remapping, it would be bound to <remap> <magit-visit-thing>.
