Enable horizontal scroll for TextEdit in Yosemite (Mac OS X 10.10.2) Is enabling horizontal scroll for TextEdit (for Mac OS X 10.10.2) possible?

After going to Preferences and checking or unchecking the box labeled "Wrap to page", the text still wraps to the next line once it reaches the end of the TextEdit window.

Wasn't horizontal scrolling possible in previous versions of Mac OS X? I feel like I'm taking crazy pills.
TextEdit doesn't work based on a page format. Since it doesn't know how wide your page is, it can't know when to wrap. You'll have to rely on something like Pages if you want to create a document based on a specific page format.
