Macbook with US keyboard running windows 7 - how do i enter euro

If you run the character map program, you can basically pick a font. Then you find the Euro sign, and on the lower left corner there will be text like "Alt+0125" so that just means if you hold down the Alt key and press the number keys 1, 2, 5 then whatever character is represented by code 125 will be inserted.

Thanks Scott
I couldn't get the ALT+ controls to work on the Mac with Windows 7 - no problem with a regular PC on Windows 7.
However, you put me on the right track. In the character map I was able to assign ALT+4 to create the euro symbol, so in effect I can replace the dollar sign by hitting ALT and the dollar key.
Problem solved thank you.
