Is there a way to make a note option button remain "on" after selecting it? I'm writing in 6/8, and it's a pain having to hit the period key every time I want a dotted quarter note.
Yup. If you click on the |Notes| menu item, there is an option called |Persistent Tools...| Click on this and there is a series of check boxes where you can select from several options for persistency. The one you want is |Augmentation Dot|
I had no idea that was there - this makes a lot of tasks much easier, so thanks for asking and answering this question I didn't even know I had!
