I don't think I've linked to this before, but Philippe Martin has one of the original and best pages of Keyboard Maestro tips.1 I love the formatting of the example macros. It's clearly a labor of love and must have taken ages to compile. The whole thing beats the pants off of the native Keyboard Maestro documentation.
I just wish it had better references and attribution. I know I've seen these before and I would really like to know the original sources. ↩
