Problem working with a tutorial speaking about how to Export a file to a PNG Transparent file?
Where is the Properties Panel in this Tutorial?

I am working in a tutorial entitled: How do I make my exported PNG image a Transparent file? Which lead me to: Exporting Icons Hands on Tutorial.
I am absolutely frustrated with this tutorial. Why?
1st of all, it is hard to work with the images in the tutorial with the instruction panel right over it all.
2nd, I am at the point where it says to Group the images I just used my selection tool to surround. But it says to find Group in the Properties panel.
I can't find the Properties Panel. I even tried to go to Window > Properties and it still doesn't show in the screen.
I am simply exasperated with this tutorial. I got to take a break on this. Why is this so darn hard to follow?
