For this specific case, see Eric's answer (if you don't want the
customization to touch your .emacs, just "set for the current
session"). Customize is considered the "Right Way" to set such
configuration items.

In general, yes: eval expression asks you to enter an expression
(in the minibuffer) which is then evaluated.

A bit more comfortable is entering the expression in a scratch
buffer which is in Lisp mode (the start-up buffer named *scratch*
fits this description -- what a coincidence ;), put point somewhat
after the expression, and hit C-x C-e ("eval-last-sexp"). This
is nice, because you can keep your expressions nicely formatted
and you can modify them until they behave the way you like.
