In FF I just click once!?!?
Yes, but in FF, if you want to edit the link, you have to click again to deselect the entire address. In Safari, it defaults to:
single-click to edit
double-click to select a "word"
triple-click to select the entire address
Neither is superior... just different approaches.
go to the beginning of a line, then hit: shift-end and it would hightlight the entire line. ... go to the middle of a line, hit shift-home and it would highlight everything BEFORE it, how do I do that?
