"How to add grace notes. Can anyone help me?"
In Finale 2003:
On the icon bar, I select the eighth-note box for "SIMPLE ENTRY TOOL"
Across the top, I now read a revised menu:
... Options Simple Trade-Up ...
I select "Simple" then select "Check for Extra Notes"
Then I was able to add a 1/32 grace notes to a dotted half in 3/4 time.
I was also able to add a slur from the grace note to the dotted half.
I was so happy to finally find this. (I was working on Minuet 2 by J. S. Bach.)
It also works in Finale NotePad 2008:
Window Help Trade-up becomes Window Help Simple Trade-Up.
Then "Simple" followed by "Check for Extra Notes on Mouse Click"
G'luck! Lisa
