That only alternates to and from Full Screen. Im trying to reduce the size of the box in the editor.
Oh – look at Screen Options – upper right – add some columns…
Im trying to reduce the EDITOR box not add anything. In the bottom right hand corner of the editor box you are supposed to be able to enlarge or reduce the box,,,,,,, It wont let me reduce the box.
I see – What browser and OS are you using?

Chrome browser with Windows 8 wordpress 3.5
Logout out of site (make sure you are – load site and if it asks for PW at /login.php you are)..close browser – open – clear browser cache – clear cookies for site…
chrome://settings/clearBrowserData
Check all except clear saved passwords (or re-enter them)..close brower – open – try again…
Also are you using the desktop Chrome or App:
Fifth item down (upper right) will launch as app or as desktop…
And – since on W8, intel or other (only new apps work)?
