Sorry for the delay firstly. I've been busy lately :D
I've read over the documentation of Highline and didn't find what I 
needed, but after it I checked out the rawline gem and I found a great 
example at the author's web 
(http://www.h3rald.com/blog/inline-introduction):


#!/usr/local/bin/ruby -w

require 'rubygems'
require 'highline/system_extensions'

include HighLine::SystemExtensions

puts "Press a key to view the corresponding ASCII code(s) (or CTRL-X to 
exit)."

loop do

    print "=> "
    char = get_character
    case char
    when ?\C-x: print "Exiting..."; exit;
    else puts "#{char.chr} [#{char}] (hex: #{char.to_s(16)})";
    end

end


...so I can use highline finally (thanks! :D)

I just don't understand one thing from the code above: the "?\C-x", in 
the when statement. Can anybody tell me what does it mean?
