How do I use a variety of mouth sets while computing lip sync from scene audio?

Here's a test clip for doing the expressions and everything together.  I'll chop it up and use it in the final animation.

My super high tech way of directing myself where and when to hit what keyboard triggers, haha. Post-it to the rescue. Yeah, I hope in future iterations, you can easily see and edit when you trigger what key and add, delete, chop, or extend the trigger events instead of catching them on the fly.

I think the decreased recording speed should help too.

Okay, I have another question on here that hopefully gets through even though I marked the question answered.  I got the different mouths and emotions to work with the "compute lip sync" thing, but I have a new need/question.  I have a handful of emotions and I want to be able to fine tune where they come in at and how long they last.  In the screenshot, you can see the "keyboard triggers A, C, W."  I tried shrinking the length of the keys and moving their boxes around (like you can see there) but that didn't really seem to do anything.

So can I do the key triggers manually in the timeline and tweak them instead of recording them live on the fly?
