Can't use an editor with syntax coloring?  ;-)

The emacs ruby-mode colors these as keywords:

	       "alias"
	       "and"
	       "begin"
	       "break"
	       "case"
	       "catch"
	       "class"
	       "def"
	       "do"
	       "elsif"
	       "else"
	       "fail"
	       "ensure"
	       "for"
	       "end"
	       "if"
	       "in"
	       "module"
	       "next"
	       "not"
	       "or"
	       "raise"
	       "redo"
	       "rescue"
	       "retry"
	       "return"
	       "then"
	       "throw"
	       "super"
	       "unless"
	       "undef"
	       "until"
	       "when"
	       "while"
	       "yield"

And these as special variables:

  nil, self, true, false, __FILE__, __LINE__

Aside from that I can only think of:

  BEGIN, END, defined?

You could also try searching the list archives.

HTH.
