I think I've found the most secret and disappointing easter egg on Mac. ⌘Fn← (Command Function Left) in Safari goes to Apple.com; does anyone know why, or when, this was added? Cmd-Fn-Up and down and right don't do anything.
I couldn't find anything on this after about 10 seconds of skim-reading on google search.
BTW I was trying to do ⇧⌘← (Shift Command Left) which selects everything to the left of the cursor.
Also noticed ⌃⌘← (Control Command Left) does some weird right-align thing.
