On a PC one has to download Maori Language packs and extras to get symbols above a letter....or scroll through thousands of symbols....on a Mac
wait for it....
EASY as blinking - HOLD the letter you want on the keyboard and a new menu appears with ALL the options of symbols above that letter
e.g. a - á ä å ā just by holding the letter on the keyboard! BOOOOOOOMMM
On a PC - faffing around with fonts so it doesn't change the size and shape of the font - I LOVE MY MAC!
