AutoCAD 2010 :: Deleting Old Custom Commands From The List

I created a command that I no longer use. I actually made a spelling error upon creating it "SUPECLOSE" and I want to delete it.

This is how I created this command: I typed in ALIASEDIT in order to add a new alias to a command.

I then clicked on the "Add" button.

In the "Alias:" field, I typed in "xx"

And in the "AutoCAD Command:" field, I typed in "SUPECLOSE" - which isn't actually an autoCAD command. "SUPERCLOSE" is the command I use to run a custom LISP routine that I created. Upon hitting pressing "OK" to this, AutoCAD prompted me with: "'SUPECLOSE' is a new command, Do you want to add this to your list of commands?"

I said yes. And then shortly afterwards realized the spelling error I had made. Problem is...I don't know how to access this list and delete the new command that I had just created (which does nothing).
