On my keyboard Charlie there is a home button that takes any page to the top. You may not have it with your apple I guess.
Ha! Well what about that. I have been using personal computers professionally and privately for about thirty years and forgot about that key.
That may be my first "seniors' moment".
The Apple keyboards have too many keys. I tend to ignore most of the extra ones except when I want to add a superscript or something tricky like that.
Ah well, I am just a slow talkin' country boy from Western Queensland. Cannot expect too much understanding of all of this whizz-bang technology, I suppose.
