If you locate you acad.pgp file on your HDD and open with Windows notepad you will be able to see all the commands available to you and there short cut key names, this file is also used to create new and user commands.
There are 24 basic commands.

You can find the file acad.pgp or any file withe the same extention this file open it with the note pad it have all the short cuts of the commands

Dear fazil mullasser,

Dear All,

Oldwas told: "Do not give me a fish but teach mehow to hunt fish".

I do notparticularlymeaningfultothe most importantquestion,butSadlkthe besttips and tricks toknowallAutoCAD commandsandtheir abbreviations, and not only thatbutyou canalso editthoseshortcutsthatyoudo not recommenddoing so-.

You can do all of this by (ALIASEDIT)command. Here are the steps:

 

* From (Ribbons Panel) > at (Express Tools) ribbon > Click (command aliases) button.

Congratulatios ;) now you can Add, Edite or Remove any of AutoCAD commands.

 

OR

 

* At (command line) just type (ALIASEDIT).

 

OR

 

* The gift, go to:

C:\\

Program Files

Autodesk

AutoCAD

UserDataCache

Support

and find there file named (acad.pgp), open it as (notepad), Or copy it to any where at your hard disk and rename it from (acad.pgp) to (acad.txt), and enjoy :)

 

You can find this file by search at your (Program Files) folder about (acad.pgp) and go on.

 

Hope it is useful.

 

Thank you

There are commands and system varibales in AutoCAD: http://www.acadclass.com/images/autocad--commands-system-variables.txt

Open acad.Pgp file with notepad and count. If you want you may change the shortcuts also.

You can use "help" to view the commands, there are many of commands available

not quantifiable since AutoCAD is being transformed time and again, but you can use hep to checck for any command

There are a lot of commands in AutoCAD.
