where is pagination in 2.6?

So I was wanting to add pagination for posts to my new blog I set up, using the default template. I was looking through the post page and didn’t see any options for pagination, looked through the settings to see if it needed to be enabled; no luck. So I turned to the docs and found this page/topic http://codex.wordpress.org/Writing_Posts#Visual_Versus_HTML_Editor which mentioned there should be a quicktag for <!–nextpage–> but that does not exist on my post toolbar, in either html or the WYSIWYG editors. Manually adding this tag to an entry just does nothing when viewing the post; it’s just one long post. I also found this link http://codex.wordpress.org/Styling_Page-Links . I did search through the forums but didn’t find much related to this, though I’m sure I looked over something. The quicktags I have are b, i, link, b-quote, del, ins, img, ul, ol, li, code, more, lookup, close tags. Has this feature been removed, or is there something else I need to enable?
