Unicode: Typing with Apple's Greek Polytonic Keyboard

I pulled the old material from my Unicode tutorial and the keyboard I had created when I heard Apple was including a Greek Polytonic Unicode keyboard with OS X 10.4. From the Tiger features page, it says,

More Languages and Scripts

Tiger includes... a new input mode for Korean and extended system fonts to support Greek (modern and classical)...

So, now the answer to the question is simple. Q: How do I type Greek using Unicode? A: Go to the International preferences pane, go to the "Input menu" tab and enable show input menu in the menu bar. Then scroll down the list and add a checkmark to "Greek Polytonic" keyboard. With that enabled, you can used the menu to go from your native language to Greek and back. Set up key combos to switch back and forth on the fly using the Keyboard preference panel.

Here is the key mapping for the extended Greek Polytonic keyboard:

Shift key down:

Option key down:

Shift + Option keys down:

It looks like the keys are mapped close to the Greek national keyboard, including:

acute	]}
grave	'
diaresis	:
circumflex	[
iota subscript	{
smooth aspirate	'
rough aspirate	"
smooth with acute	/
rough with acute	?
smooth with grave	=
rough with grave	+
smooth with circumflex	-
rough with circumflex	_
question mark	q
bicolon	Q
terminal sigma	w
acute with diaresis	W
upsilon	Y
theta	U
omega	v
xi	j
phi	f
chi	x

You type the accent first, then the character and it combines into one character. Voila.
