`showInvisibles`	Show invisible characters (e.g., spaces, tabs, newline characters). Default value is FALSE
`showPrintMargin`	Show print margin. Default value is True
`border`	Set the `border` 'normal', 'alert', or 'flash'.
`autoComplete`	Enable/Disable code completion. See `aceEditor` for details.
