Lee Ambrosius has made available a free AutoCAD Quick Guide and announced this in a post on his blog Beyond the UI.
" Quick Guides are great if you teach AutoCAD classes to new students. One of the Quick Guides that I have is for many of the commonly used Command Aliases, Accelerated Keys (Keyboard Shortcuts), Coordinate System (Types of Point Entry), Drag ‘n Droppable files, Object Snaps and Selection Methods."
