Okay, this has tripped me up a few times because I can never remember exactly where to turn on word wrap in Aptana, and for some strange reason the developers decided to leave this commonly needed (to say the least) function off by default.  This is partly due to the fact that Aptana has more than one section for “editors” in the preferences menu.  One of them is “Window” -> “Preferences” -> “General” -> “Editors”.  The other is in “Window” -> “Preferences” -> “General” -> “Aptana”.  The second location is the one we’re looking for.  Aptana also happens to be one of the few standalone IDE environments for the Apple iPhone… unfortunately, they may only bring this feature back if savvy readers like you vote.
