Forum:Moving a page for disambiguation

I feel a bit of an idiot asking this, but how exactly do you move a page to disambiguate it from a similar (albeit currently without a page) concept? Searching through the archives, Forum: How do I move pages and categories? mentions a "move button", but I can't actually find said button. 94.6.86.58 10:19, July 12, 2011 (UTC)
