There is a button near the bottom of the screen labeled Options, which will bring up the Options Dialog. For a description of the available options, see the Options Reference section.
To the right of the Options button is the Key button. It brings up a dialog with the Key note and a Minor checkbox. These options are the same as the Key and Minor options on the Scale Tab of the Options Dialog, but with the addition of the following single-keystroke shortcuts:
|a through g||Set key|
|m||Toggle minor mode|
|+ or UP||Up a half step|
|- or DOWN||Down a half step|
