I am surprised at the "ageist" tone I perceive in some of the posts e.g.
Considering her age, she will probably be using a limited number of programs.
My experience with people of that age is that they don't relate to icons and will expect the top left hand one (for example) to always do the same thing regardless of what little picture is there.
I would imagine that someone of a mature age would find pressing two keys simultaneously, even with sticky keys enabled, much harder (physically, and maybe conceptually) that just tapping an icon with their finger
. I realise you are trying to be helpful but it comes across as a little patronising. In my experience older people pick up new things just as easily as youngsters, they usually have a longer attention span and are prepared to work at something until they get it.
