docs: Ask the server to perform an operation on a range (sometimes named point)
  
          `what` is used as the prefix for the typehint.
  
          If `useSelection` is `False` the range is calculated based on the word under de
          cursor. Current selection start and end is used as the range otherwise.
  
          `where` defines the name of the property holding the range info within the request.
          Default value is 'range' but 'point' is sometimes used
