The LispWorks editor is fully integrated into the LispWorks programming environment. If you do not currently have an Editor (check the Window menu), start one by choosing Window > Tools > Editor or clicking on 
in the LispWorks toolbar.
There are a number of editor operations which are only available in Listener windows (for example, operations using the command history). These operations are covered in the LispWorks IDE User Guide.
