We use computers everyday and the 'F" keys, or function keys sit right at the top.....but do you use them? I have to say no..... well a couple, but I could probably use a few more now that I can print this out and have it front of me. I'm a visual person and unless I use it all the time I'm not going to remember what they're for. It's a bit like my license number. I write it down several times a day (my son has his L's) but do you think I can remember it? Not a chance.
This might help more people, just like me, who have memories like sieves..lol
