Here's a question which may not belong in this group, but I wasn't sure where
else to post it.  It's a typing question.  Not being a formally trainded 
typist, I was wondering if anyone out there used their third finger on 'r'.
Normally I use my index finger, but the 'rt' combination is so frequent that
at times it seems easier to use the third finger on 'r' and then the index
on 't'.  Is there an "officially sanctioned" method?  Once again, my
apologies if there was a better place to post this question.  

Thanks,
Mike
