Hi Wardred, it may seem old-fashioned, but when I was in class for 3D graphics, I used to keep a notebook right next to me and jot down the hotkeys to the software I was learning. The act of writing it down helped my brain make those connections to the material. There are other instructors out there that have made electronic cheat sheets and offer the PDF for just signing up to their websites. CG Boost is one example.
