This is one of favorite keynote tips/tricks. It greatly enhances productivity.
Having Multiple inspectors in Keynote will dramatically improve your productivity especially if you are using keynote as an animation tool. At first I was only using one inspector and I had to click between the build, text, graphic, and metrics pallettes when editing my dots. I found a simple trick to create multiple inspectors. The trick is to simply option + click on the palette and a second inspector will appear. You can do this for as many times as you need inspectors. That is how you create multiple inspectors and thanks for watching.
