korean altGr keys in windows 7 OSK

Can some one provide me list of AltGr keys for korean language for use in windows on screen keyborad.

How to change the keyboard language from English to Korean by pressing ALT hotkey.

Press the Windows key
Search "Region and Language" and open the first result from the Control Panel
Go to the 3rd tab "Keyboards and Languages" and click "Change keyboards..."

Click Add and add KO Korean (Korea)
Then change " Default input language" to "Korean (Korea) - Microsoft IME"
**Don't worry you will still be able to type in Korean & English**

Save & Close

You should now have the language bar docked to your taskbar and it should say
"KO (world and pencil Symbol) A (Question Mark)"

Now all you have to do is press the RIGHT ALT button whenever you're in a TEXT FIELD to change from "A" to "가"

Hope this helps?
