Anime shorthands

Hello forum go-ers!

This is a question mainly for those working in anime, but can also extend to anyone else.

I want to know your best shorthand when animating or any time saving tricks that you might have.
For example:
A piece of advice I saw on here for animating dialogue was by using just 4 mouth shapes for convincing but limited lip sync; closed, semi open, fully open and “o” sound and ordering them thusly 1, 3, 2, 3, 2, then repeat, adding the “o” where necesary.

What are your favourites or what has helped you get an assigment in before a tight deadline?
