On SBCL, describing a bound symbol generates a HUGE wall of text with all the slots of the bound class, all the methods of the bound function etc. For nyxt:buffer, it's:

BUFFER names the user-class #<NYXT:USER-CLASS NYXT:BUFFER>:
  Documentation:
    A buffer is the fundamental unit of displayed content.
    Buffers result from the computations of a web renderer, which generates a visual
    representation of HTML documents.
    
    Rendered URLs or the Nyxt's manual qualify as examples.  Buffers are fully
    separated from one another, so that each has its own behavior and settings.

What would be good for this workflow, actually, is using the function that represents the field as the field name. E.g., use find-class instead of class-binding in

CLASS-BINDING     = #<NYXT:USER-CLASS NYXT:BUFFER>
