Good post, I'm (more or less) an emacs guy, but vimtutor + this + 1 to 2 days of my time might certainly convince me of switching to vim.<p>(warning, by no means am I trying to instigate yet another emacs vs vim thread but here I go)<p>Not to hate on emacs, since it has served me well as an advanced editor for the past year or so, but I sometimes feel so lost in its sea of features and a never-ending config file that I often end up saying to myself "If I only I could take the time to learn lisp maybe I could <i>really</i> start using emacs that way it should be used", nevertheless, learning vim versus learning lisp is certainly more cost-effective for my time.
tab completion also works for help: it cycles through all help keywords that contain the present text (not just suffixes, as in normal tab-completion). eg. try<p><pre><code> :he lvis
</code></pre>
and press tab.<p>I like the inline arithmetic:<p><pre><code> CTRL-R=5*5
</code></pre>
Note the "=" comes first. I just discovered that "CTRL-R5" inserts that line from your cut-and-paste history (or something).
