How to Superscript and Subscript in Microsoft Office Word?
In earlier version of Microsoft Office (Word 2003), trying to write a subscript or superscript takes quite a time but with the new Word 2007 it’s so simple. For those who are writing technical articles face situation to use these subscripts and superscripts in almost every article like mathematical formulae or chemical equations.
What are Subscript and Superscript? A subscript appears smaller and below the baseline (Ex. H2O or X2) while a superscript appears smaller and above the baseline (Ex. X3)
How to Subscript and Superscript in Office 2003 and 2007?
In Word 2003, select the characters that you would like to change. Go to Format menu and Click Font, from the Font tab you have to select subscript or superscript.
In Word 2007, select the character that you would like to change and Click the Superscript or Subscript symbol from the ribbon under the home tab.

In both Word 2003 and Word 2007, you can also use keyboard Shortcut keys to make the characters as Subscript or Superscript.
Superscript: Press CTRL+SHIFT+=
Subscript: Press CTRL+=
