What key do you use to superscript in a Hotmail document?

For Windows 7, the method I use when in the middle of composing an email is to click on "START" and find (or search) for the Character Map. Click on the character you want followed by "Select" then "Copy". Now return to your hotmail letter and do a Right-click, Paste. Unfortunately, my method pastes the special character at the beginning of the next line so I have to do the following sequence: backspace-left arrow-backspace. This should put the special character where you wanted it.
