Sorry, didn't realize we already had `find()`.

Regarding the options: you are making the calls to the function more explicit while at the same time making the declaration of the function less so. Also (though it's a minor thing) you're making life harder for javascript compiler which tries optimizing this code. In my opinion, the best solution is to have the boolean argument here and in places where it is not obvious what the call argument means, add a short comment like this: `this.editor_.findNext(true /* reverse */);`.

Let's hope the named arguments will appear one day in JavaScript.
