I have found that the easiest way to use the fada in these posts (if you are using Windows) is to go to Control Panel, choose Keyboard and then go to the tab for language. You install "English (Ireland)" as one of your choices. Then when you want to type using fada's you simply go to the tray at the bottom right of your screen and click on the box labeled "En" and choose the English (Ireland) as the default. To get a letter with a fada you simply hold down the alt key while typing it. Hence á or Á. When you are done with it, just go down and click on the "En" and change it back. It is very easy. The only thing to watch for is that the Irish and American keyboards are different so the @ sign and the " sign are switched. I am sure that there are other differences but they are easily figured out.
