    #                       Button Binding Description

    #

    #     The syntax for this type of structure is as follows:

    #

    #     buttons bindings_set_name

    #     {

    #         button     context     function

    #                :

    #         button     context     function

    #     }

    #

    #     The syntax for the context specification is

    #

    #     context = object[|context]

    #     object  = root | icon | window | title | frame | border | app

    #

    #     The context specification indicates where the mouse cursor must be for the

    #     button binding to be effective. For example, a context of `window' indicates

    #     that the pointer must be over a client window or window manager frame for

    #     the button binding to be effective. The `frame' context is for the window

    #     manager frame around a client window (including the border and titlebar),

    #     the `border' context is for the border part of the window manager frame

    #     (not including the titlebar), the `title' context is for the title area of

    #     the window manager frame, and the `app' context is for the application window

    #     (not including the window manager frame).

    #

    #     If a function is specified in a type of resource where it is not supported

    #     or is invoked in a context that does not apply, the function is treated as

    #     f.nop (no operation is performed).
