I found this cool list of cheat cheats on a site called Design Bread...
Cheat sheets are a great way to have references on hand for everything from shortcuts and hot keys, to handy tips to improve your workflow. Be sure to browse the whole page and see all of the categories! Book mark this page also so that the next time you are looking for a particular cheat sheet you can just come right here and find it quickly!
Find cheat sheets for Video programs, Image Editing Programs, Web Languages, SEO, Social Media, and even Photography. They will add more, so check back occasionallly.
I'll add the link to our Resources page too.
Enjoy!
