 The editor in Wordpress 4.1 is great, and the whole sticky sidebar is a
 great improvement, but editing using Page Down and Page Up keys as part of
 the workflow is some of the most frustrating experience one can have
 because they control both the cursor in the post edit box and the page
 itself.

 For example, if I go into a short post, put the cursor at the beginning of
 the post, and press Page Down, I'm going to end up with this:

 At this point, I can only see a tiny sliver of the post because the page
 has scrolled too.

 This is similar to #30919, except I'm not talking about the distraction-
 free mode, which I almost never use.

 Windows 8.1 on Chrome 42 beta, but this behavior has been the same for as
 long as I can remember.
