I’ve always found it a real pain to quickly and easily insert Irish/French/Hungarian (or other) language characters (i.e. vowels with fadas over them) into documents on Microsoft Windows, then let there be pain no more. A simple matter of pressing the Alt Gr key whilst also pressing the desired vowel does the trick very nicely.
I’m sure this may be well known to some/many of you but it was news to me and will save me a good bit of time as a number of colleagues have names with Irish/Foreign letters in them.
Credit goes to John Mernin for alerting me to this.
