I know that I can just browse the web for these words but is there a way to just let Ruby do it for me? You don't have to give me a whole program, just some hints to let me go about it. Thanks in advance.

You can't get Ruby to do this for you.
However, here's the list from Dave Thomas's Programming Ruby 1.9, The Pragmatic Programmers' Guide (Also known as the Pickaxe):
__FILE__,__LINE__, BEGIN, END, alias, and, begin, break, case, class, def, defined?, do, else, elsif, end, ensure, false, for, if, in module, next, nil, not, or, redo, rescue, retry, return, self, super, then, true, undef, unless, until, when, while, yield
