Heck yes! The new Keyboard Maestro Field Guide is the perfect intersection for my favorite Mac Utility and my favorite Apple Nerd. These are so great. Not only is the video a great way to learn Keyboard Maestro, but each segment contains a transcription and downloadable macros.
I'll buy pretty much everything that David Sparks does. It is top quality and presented with enthusiasm and joy. For $ 24, I think this is a bargain. If you do not own Keyboard Maestro yet, I strongly recommend buying this course and see what you have missed out on your entire Mac life. It's an amazing tool that I use every few minutes I'm on my Mac.
