Sample doc isn't editable affect, presumably to hide the fact that in addition to overriding standard scrolling it also doesn't support international text entry or, 50/50, standard and custom key shortcuts from the OS [edit: I was right - cmd-f doesn't use the proper find ui, cmd-e doesn't update the search pasteboard, and cmd-f doesn't track the system search pasteboard.]
