1. You can drag any of the palettes around the screen by pressing and holding the space bar while clicking on a palette and moving it.
2. When you want to change the shape of an object in relation to itself instead of where it's at in the space click on the down arrow next to the edit button click on the object option.
4. To duplicate an object click it so it's highlighted and then press CTRL+D.
5. To change an object into a different one (i.e., sphere to torus) while maintaining it's original proporations use number 4 above to duplicate and in the edit menu towards the right there are two little arrows facing away from each other, click on them and select a different shape and that object magically changes to it.
More to come but I'm sure most of you already know these. I'll list more technical ones when I get home.
