I am trying to learn how to use ri effectively. I was looking up
methods for an Array. If I type Array.methods.sort at the irb prompt,
it displays a whole slew of methods. If I then type "ri Array.sort" at
the command prompt then I get a brief description of it. I noticed that
Array class has an "&" method. I am trying to look it up using ri as
follows:
ri Array.&
It does not work. How do I lookup the "&" method for an Array class
using ri?
Another question related to ri is that if I type
ri Array
I get a whole lot of stuff on the Array class. It seems like the screen
buffer responds to "vi" style movement keys, e.g., CTRL-F for forward
one screen CTRL-B for one screen back,etc. I noticed that the
documentation says "&" is an Instance method and the screen prompt waits
at ":", is there any command that I can type here which will get me more
info on the desired method listed such as "&" for example?
Is there a brief how to guide available for using "ri"?
Thanks.

You should use # as a separator, try e.g. 'Array#&'.

The ri(1) manual page has some information.. but I'm sure that you'd like a
better (and way faster) tool: try fastri http://eigenclass.org/hiki.rb?fastri
You should surround the argument with ' or ", since "&" has a special meaning
for the shell :
ri 'Array.&'
ri --help warns about this issue, and gives the basic of its use.
