First of all I fire up irb and just try a couple of likely names and
argument lists, many times that "just works" as I get more used to Ruby.
irb is a quick way to learn by doing...

If that fails, then I look in my copy of Programming Ruby at the Built-In
Classes and Methods section if I can, failing that (e.g. when at work) I
go on line - in this case to http://www.rubycentral.com/book/builtins.html
- and look for a likely method name.  Once I have read the description
I try it in irb to see if I have understood what I read.

That's what I did this time, if that hadn't worked then I would have searched
on google for

  ruby substr

and found something like

  www.zenspider.com/Languages/Ruby/Cookbook/Strings/AccessingSubstrings.html

Hope this helps,

Mike
