Sure, but with a leader key in vim set to 'f', I can save with f-s (that is, press the f key and then the s key), which after a month is next to automatic
You’re arguing about vim shortcuts in reply to a description of what one can do if one doesn’t want vim shortcuts. Note that the equivalent in vim is not really f s, but ESC f s, because in most modes where one might do M-m f s, most characters insert themselves, the equivalent of insert mode in vim.
Note also that in regular emacs one can do C-x C-s (ie holding control press x then s).
