AutoCAD 2012 now offers auto-complete options to help you access commands more efficiently. As you type in the Command prompt (or use dynamic input), AutoCAD automatically completes the entry with an AutoCAD command or command alias. If you pause, it displays a list of all the commands whose prefix matches what you’ve typed, enabling you to scroll and select from the list.
A right-click menu provides easy access to the new AutoComplete controls, including the ability to display system variables and specify the delay response for displaying the AutoComplete list.
In the Command window, the command history is distinguished from the active command line with a grey background color. You can modify the various colors associated with the command window using the Drawing Window Colors dialog box, which is accessible from the Display tab of the Options dialog box.
