AutoCAD Troubleshooting: Typing Commands (Aliases) Too Fast Opens An Incorrect Command. Why?

When I type commands quickly (using aliases) sometimes the incorrect command is executed? Why?...

Issue/Problem: 

If you primarily use the command line to enter commands (or a combination of keyboard and mouse to enter commands), you have likely noticed that on occasion an incorrect command (commands with similar aliases) was executed in-place of what you expected. For users that routinely enter commands from the keyboard, the lag/delay of AutoCorrect/AutoComplete can prove frustrating (vs. ribbon/menu selection).

Example

To start the COPY command (alias CO for Copy), type CO in the command line and either press Enter (or alternatively, Right-Click to start the command).

If the user enters the text too quickly, the software may not acknowledge all keystrokes. For example, the software will noticed the C but not the O keystroke, thus starting the CIRCLE command (alias C for Circle) instead.

Solution:

Enter the command INPUTSEARCHOPTIONS which lets the user adjust the list delay time (default is 300 milliseconds). The value can be adjusted up to a maximum delay of 5000 (5 seconds).

For users that are fast-typists, setting the delay to 700 milliseconds tends to resolve the input lag issue. You can set the value higher, however that may cause too much of a delay. Adjust to suit your input speed.

Alternatively, you can disable the feature for certain commands by toggling off the respective checkbox.
