LispWorks now adds a minimal
menu to all CAPI interfaces when running in the LispWorks IDE, which makes the edit gestures
work in every interface displayed in the LispWorks IDE.
However, to implement these gestures in your CAPI/Cocoa runtime application, you must include an Edit menu explicitly in your interface definition, as described in Adding menus.
To remove the automatic menu when running your program in the LispWorks IDE, pass the initarg
when making the interface.
