shouldSuppressAutocorrectionAndAutocaptializationInHiddenEditableAreasForHost(...)
Apple-style function/method naming may be verbose but at least the names usually have good explanatory value and aren't just meaningless verbosity.
Also, autocomplete doesn't work when you're reading and not writing, or just using a text editor or reading/annotating a printout (yes, I still do that.) IMHO writing code that almost completely relies on special tools to handle it is a bad trend.
