Rated 4 out of 5 stars

Just great, it does almost exactly what I was looking for, plus some more.

I personnaly added 10 lines of js in order to be able to type in
a b c foobar
instead of
@a,b,c foobar

(question of taste and @-key location on french keyboards :)

Thanks alot!!

Interesting

In your case are `a b c` search engine keywords or just the initials of the search engine.
