    Select the lines you want to comment out, and do CMD+/ (forward slash) on a Mac. On a PC I'm assuming the same thing is CTRL+/
You can un-comment the same way, and you can also comment single lines out with the same keystroke. It doesn't really matter where your cursor is on the line. As long as a part of the line has been selected, the comment will include the whole line.
 
    
    Ruby does have multiline comments, although they use a relatively strange syntax:
=begin
some text or code here
=end
Note that both the =begin and =end delimiters have to be at the very beginning of the line, nothing else should be on the same line.
 
    
    to comment some think like this
=begin
  your code is commented out
  this line is also commented
=end
select lines and press ctrl+shift+/ to comments some think like this
#your code is commented out
#this line is also commented
select lines and press ctrl+/
