Hi, beth. You can create a "formatted text" autocorrect entry. To do this
for mu, type a µ, select it, click on Tools | AutoCorrect Options |
AutoCorrect | Replace: mu | With: µ | click the "Formatted text" radio button
| OK.

I want to change 'mu' to the greek letter mu, 'sigma' to the greek lower-case
symbol sigma, etc, in the autocorrect feature. There is no option for
changing font in the autocorrect. How can I do this?
