MS word has capability to customize toolbars with shortcut buttons for
"superscript" and "subscript". This feature has never been added to Excel
for some reason. It would be really helpful for those of us in chemistry and
math related fields for writing out chemicals like CO2 and formulas like A =
pi*r^2.

Currently the only way it can done is through format cells menu item which
becomes tedious after 2 or 3 uses. Can this feature be added in soon???
With a service pack update even?
