quicko: hide and go R

It shouldn't really be a surprise in English, but the R is a particular tell-tale letter in terms of where you learned to speak.  As in, do you use Rs or not?  Do you add extra ones before vowels, just because?  Australians do.  (For example, we stand in "awe-R" of God.)  But then sometimes they disappear in other places.  It's all very complicated.  And goodness, that's to say nothing of the mighty O!
