I seem to be finding a lot of useful(for my style of working anyway) little options for AI lately...

This one is a quick object lock. A speedhack if you are setting up a template with a lot of objects, you would probably know how annoying it is to break your flow of work by having to search and lock layers you are selecting/creating. Well here is the solution: CMD+2

Poof, insta locked layer.

Just a quick AI tip that I stumbled upon today, most might know it but I didn't so why not pass it on?

Everything within a layer is its own object, and if say, you have an outline shadow of text that is two layers down that a customer just wants to make a quick color change to....You don't want to have to dig through ALL the objects in said layer. Just select any object within that layer (the one closest to the object you are trying to get to would be best.) and use CMD+OPT+[ or ] to scroll quickly through them.

Edit: ..... :)
