While M-f, M-b are e and b, I don't know of an exact equivalent for E and B. But they could very easily be added.
IMHO, basic editing in Emacs has slightly higher constant factors (mostly due to typing the modifier keys), but scales much better as operations become more complex.
As for adding equivalents to E and B, sure, but what keys do you bind 'em to? Either unwieldy C-c FOO combinations, or spend the rest of forever playing whack-a-mole with various modes that happen to have already defined the keys you wanted to use. While emacs is infinitely customizable, the baseline editing functionality that everything expects is important -- otherwise you're just fighting against the grain. Though the various vim emulation modes have made a heroic effort...
It would be interesting if something like that vim keystroke competition could be expanded to include emacs as well. >:)
"Super"-f/b are free on my keyboard, where "super" is the button with the Windows logo on it. I don't really miss the E/B functionality, though, and I used vim for about five years before I started using Emacs.
(BTW/FWIW, I'm on mac and keep the option key as command, so no extra key lying around for me to use as super.)
I'm easily sucked into vi / emacs threads, and I've talked about this at length a few times. I have a bit over five year experience with each, at this point. I prefer vi's general keyboard interface design (edit vs insert mode, etc.), because it gets rid of most of the modal keys that Emacs uses, but strongly prefer Emacs's "continuous environment"/integration and general extensibility. On the balance, I prefer Emacs. (And while there are vi-emulation modes for Emacs, such as viper, few extensions provide vi-like keybindings for them.)
For "." you could say that C+k,C+_/C+y does most of what I want done -- and arguably, the more complex cases might be amenable to using regexp-replace.
Regretfully, the only time I ever use hjkl is to play crawl :) The emacs keys are perhaps more geared towards using modifiers, with M-f/M-b + C-f/C-b serving as the closest replacements for movement, and M-z for zap-to-char.
gin17 ~ $ time emacs --eval '(save-buffers-kill-emacs)'
real 0m0.256s
gin17 ~ $ time vim --cmd :q
real 0m0.006s
Well, after all this discussion, I'm probably morally obligated to spend more time with vim (or maybe vimpulse) so that I actually know what I'm talking about. :)
But e.g., stuff like "." the e/E and b/B distinction, [d]f (like zap-to-char but waaay more useful) don't really have emacs equivalents.
And come on, C-f, C-b, C-n, C-p to move around -- not smart! I assume it's for "forward, backward, next, previous", but you shouldn't choose your most basic motion keys to have memorable names, you should choose them to be efficient!
