Michaelr, there are a number of threads in the Forum which would show you how to do the fadas. I can't find a good one, but I'll show you a method which is fairly easy to remember.

á = á
é = é
í = í
ó = ó
ú = ú

There. That gives you the IRish vowels with their method of entry. For vowels with grave accents (ones angled the other way), substitute the word acute with the word grave

Does that make sense to you, Michaelr? IF not, PM me, for details.
