This document provides a summary of common shortcut keys in AutoCAD for 2D drawing, modifying objects, general navigation, 3D modeling, 3D modifying, and lighting/materials. Some of the most frequently used shortcuts include L for lines, E for erasing objects, AR for arraying objects, Z for zooming, and SHA for shading mode. The shortcuts allow users to draw and modify both 2D and 3D objects as well as navigate around drawings efficiently in AutoCAD.
