A great place to learn, well nearly everything, is at lynda.com. They provide software training for many software programs. I generally visit when I need a quick answer for Illustrator or Photoshop, but it has also been helpful when learning a whole new skill set – like Keynote.
And truth be told – I have used it extensively for Excel… Not a fan!
You can preview some videos before you buy. For the membership cost of just under $400, you get access to any and all videos for a full year. That amount doesn’t even start to cover your three-day conference registration fee, along with travel and hotel!
Plus, you can view them anytime, anywhere.
