I've written a cross-reference lsit for AutoCAD's CUI (command user interface) dialog box. Unfortunately, CUI does not list commands by their names, but by their menu descriptions. This flaw makes it difficult to find commands.
The chart lists in alphabetical order the AutoCAD commands used by CUI, along with their CUI descriptions and macros. Some commands are undocumented by Autodesk, others are system variables. Command names are sorted in the order of A, AI, B, C, D, DIM, E, ..., Z, 3, and Miscellaneous.
Caution: With over 500 commands listed on these eleven pages, there are bound to be some errors. This list was based on the AutoCAD 2007 of CUI, which itself makes some mistakes, such as including certain discontinued commands.
