I dug out the info on where to find the Character Map. You have to go back to the desktop and click "Start", select "Programs" and then "Accessories". When the Character Map comes up you will see a display of all the possible symbols in all of the fonts in your machine. You need to select "System" as the font and then you will find the needed symbol in the display that comes up.
Looking at the bottom right of the display should get you the keyboard shortcut for each symbol you want. HTH.
