So what are Quick Guides you might be asking? Typically, Quick Guides are focused on a specific topic and deliver a quick shot of information and might be enough for a general overview at times of some features. They might also be references that are able to get you up and running very quickly with new features or even old ones that might have been forgotten. Quick Guides are currently being published for General Usage of the software,
Commands,
System Variables and Environment Variables.
General Reference Quick Guides
The General Quick Reference Guides contain commonly used Command Aliases, Accelerated Keys (Keyboard Shortcuts), Coordinate System (Types of Point Entry), Drag 'n Droppable files, Object Snaps and Selection Methods.
Environment Variables Quick Guide
Environment Variables are similar to System Variables, but they require a different way of accessing them and they are stored in the Windows Registry.
