I edited the title of this question to remove the
\displaystyle in the title, but, in the process, I deleted a brace. As a result, it won't compile; but the edit has been accepted. (As far as I could tell, the preview window shows only a preview of the body, not the title; is this correct? Is there any way to see how the title will (or won't) render before attempting the edit?)
I can't insert the brace (it's too small an edit). Would it be possible for a moderator to fix my goof?
