Hey, this is really great (and a strange coincidence -- this afternoon I was thinking about building something similar).

Something I'm wondering about: I currently use vim-latexsuite which has a bunch of expansion features. For instance, if you type '^^' it expands to '^{<++>}<++>', where the '<++>' are jump markers, and then 'jumps' into the first marker. So if I wanted to type e.g., 'e^{-x/2}', the keystrokes I'd use would be 'e ^ ^ - x / 2 CTRL-J'.

I'm not sure how you'd do the something similar, but the combination of jump markers and user-defined expansions (e.g., I can define 'QQ' -> '\mathbb{Q}', 'fN' -> 'function', '`/' -> '\frac{<++>}{<++>}<++>' or even 'pmABCD' -> '\begin{pmatrix} a & b \\ c& d \end{pmatrix}' ) saves an enormous amount of time writing TeX.

Out of curiosity, why do all these in your editor rather than in TeX? For example, `\def\QQ{\mathbb Q}` would work just fine, and be only one more keystroke. (The third example could be made into a parametrised macro, but `\frac` is already such a macro, so I guess that you're really valuing the keystrokes.)

It sort of depends. For the blackboard bold, it's not really much difference between doing it in the editor and doing it as TeX macros. I used to do them in TeX, but after I started doing other things in the editor I switched them for no particular reason outside of consistency. Also, expansions for words like function, holomorphic, 'the following are equivalent', 'if and only if', etc., are problematic to do as TeX macros, because of issues around spacing, and because it's simply more readable.

For the others, it is really about the keystrokes -- one has to be able to type really fast to keep up in a lecture or a talk, and then once you've optimized for speed, why not type that quickly all the time?

Pleased to hear it wasn't a mad idea to build the site! I don't personally write the vim command and tbh they are just vi movement bindings which come along with the ace editor - http://ace.ajax.org/

I am an avid vim user and I would also love more powerful bindings.
