fyi, using version 9.01, on windows 7, the steps are
Carm Ctrl+k then hit ENTER and continue typing.
i.e. hitting ENTER will automatically select the top and only choice and move the cursor to the end of the current word. Then if one continues typing, then this will automatically remove that small another window that comes up.
