Subject: RubyNuby Q: Howto Ri

Hi,

 Suppose I want to get an info from ri about Integers.

 In a code I found

	17.step(self,2)

 and I would like to ask ri about this construct.

 I typed

   ri Integer

 and got

    ----------------------------------------------- Class: Integer < Numeric
         +Integer+ is the basis for the two concrete classes that hold whole
         numbers, +Bignum+ and +Fixnum+.
    
    ------------------------------------------------------------------------
    
    
    Includes:
    ---------
         Precision(prec, prec_f, prec_i)
    
    
    Class methods:
    --------------
         induced_from
    
    
    Instance methods:
    -----------------
         ceil, chr, downto, floor, integer?, next, round, succ, times, to_i,
         to_int, truncate, upto


 there is nothing mentioned about "step"...so I did something wrong
 here.

 So...what should I feed into ri to get an appropiate answer.
 ("step" is only an example...)

 Have a nice and ruby day!
