I have a question regarding MS Word 2003. I could find nothing in the help
section about this. I am trying to use the find and replace option. The file
I am using it on is for music lyrics and chords right above the lyrics that I
have typed. I wanted to change the chords by using the replace function. The
problem however is that sometimes I need to replace one letter with a double
letter, like G with Bb, or D with Eb, exactly how that appears, one capital
letter and one lowercase letter. When I try to do this, it makes the second
letter a capital letter as well, even when I go to the format option in
replace and check the box small caps, or even uncheck it, or leave it shaded.
None of these work when I hit replace or replace all. How can I make it so
that the first letter that I want to have as the replacement will be
capitalized and the second letter will be lowercase?
