title: Ace editor: disable vertical scrolling
body: <p>I would like to eliminate the vertical scrollbar in my Ace Editor (that I’m embedding in a Ruby on Rails platform). I understand how to <em>hide</em> it (given the methods provided through the editor API), but not how to eliminate the capability altogether (which I believe must be done in the editor’s actual javascript). Basically, I would like an editor of a fixed length/number of lines, to which no additional lines may be added by a user. Any ideas?</p>
