The EquPixy 2.1 add-in for Microsoft Word will help you to work with chemical formulas and equations. The figures that designate the number of atoms in chemical formulas are automatically converted into subscripts, and the ion charge numbers and atom oxidation degrees are converted into superscripts. The function of writing a capital or lowercase letter depending on the length of pushing down the keyboard key is available for writing chemical elements; if you push down and immediately release the key, a capital letter is written, if you push down the key and hold it for a second a lowercase letter is written. The EquPixy add-in has the ability of checking the validity of chemical equations for the required number of elements on their right and left sides. Other useful functions are also available. For example, the generation of an arrow with indication of reaction conditions, etc.
