1. If the Score Structure panel is not already visible on your screen, choose Score Structure Panel... from the Tools menu to make it visible.
2. If the Clefs & Key Signature pane (which contains the tabs: Clefs and Key Signatures) is not visible in the Score Structure Panel, select Clefs & Key Signature from the Available Panes pull-down menu at the top of the Score Structure Panel.
3. Choose between the two tabs in the Clefs & Key Signature pane to view controls for Clefs or Key Signatures.

Clefs Tab

The Insert Clef pane is used for temporarily changing clefs on the staves in your score.

There are nineteen clef types available in NoteAbilityPro:

	Treble clef		Alto clef		Tenor clef		Bass clef
	Treble Octava Up clef		Treble Octava Down clef		Bass Octava Down clef		Percussion clef
	No clef		Treble Double Octava Up clef		Bass Double Octava Down clef		French clef
	Baritone C clef		Mezzo C clef		Soprano C clef		Baritone F clef
	Basso F clef		Percussion clef (alternate)		Bass Octava Up Clef

To insert a clef, place the Entry Cursor at the beat location where the new clef should begin. Choose the new clef to be inserted by adjusting the slider until the desired clef appears, then set whether images should be:

1. adjusted until the next clef change on the same staff,
2. adjusted until the end of the score (which will remove all other inserted clefs to the end of the score),
3. left where they are and just insert the clef.

Click on the Insert Clef button. The clef will appear to the left of the Entry Cursor (and it may be adjusted later to avoid collisions with other images). If the Entry Cursor has been placed on the first beat of a measure, the clef will appear at the end of the previous measure. In the example below, the Entry Cursor was placed on beat 2 of the second measure and a treble clef was inserted, then the Entry Cursor was placed on beat 2 of the third measure and an alto clef was inserted.

If you only want to change a clef for a short duration of your score, you can set the number of quarter note beats that the new clef is needed and click on the Change Clef button. This operation will insert the new clef at the Entry Cursor and then insert the original clef after the specified number of beats. This operation is useful if you are altering clefs after notes have already been added to the score. Here, only the notes between the two clefs will be changed to the correspond to the new clef. In the example below, a treble clef is needed only for the last beat of each measure. Place the Entry Cursor on beat 3 of the first measure, adjust the slider so that a treble clef is displayed, set the duration to 1.0 beats, and click on the Change Clef button. Repeat the same procedure on the next measure.

Key Signatures Tab

The Key Signatures tab view is used insert or change key signatures in your score.

In NoteAbilityPro, key signatures appear only at the beginning of measures, although not all staves in the system are required to have the same key signature.

To change the key signature, place the Entry Cursor in the measure where the key signature change will occur. Select the new key signature using the slider. Choose whether the new key signature will be added only on the staff that the Entry Cursor is on or on all staves in the system. Choose whether the keys signature will be added:

1. only for the selected measure,
2. until the next key change,
3. until the end of the score,

then click on the Change Key Signature button.

The other buttons on the Key Signatures pane allow you to hide or show the key signature or to hide the key signature on only one staff. In each case the Entry Cursor should be placed in the correct measure before the button is clicked

When new key signatures are added, a thin double barline is inserted. If desired, this barline can be altered using the Barline tab in the Barlines & Braces pane in the Score Structure panel.

If the Use Naturals check box is selected, then the new key signature will include accidentals which cancel the previous key signature (as in the example below).

In addition to the standard flat and sharp key signatures, each score can have 2 custom key signatures which can include combinations of sharps and flats as well as quarter tones. These custom key signatures appear in the last 2 positions of the key signature slider. To create custom key signatures, use the Custom Key Signature Panel in the Tools menu.

- Graphical versions of key signatures are available for unusual circumstances (eg. cautionary key signatures). There is also a set of graphical key signatures with naturals so you can include cancellation key signatures as in the example below which is changing from B major to Bb major between the end of one system and the beginning of the next. (The commands used to add the cautionary key signatures were "knb" and "kbb" for key-natural-B and key-Bb.)

Menu items

The pull down menu located at the top-right corner of this pane contains items to Hide or Show key signatures in your score and to remove graphic clefs from the score.

The Remove Graphic Clef menu item can be used to remove clefs that have been added as graphic images. Graphic clefs are entered by using commands (eg !tc, !bc15 rather than by using the Insert Clef button on this panel).

The Hide Key Signature and Show Key Signature menu items are used for hiding or unhiding previously hidden key signatures. In both cases, the Entry Cursor must be placed in the measure that the key signature appears in. All existing key signatures in that measure will be hidden or shown. If you only want to hide the key signature on one staff, place the Entry Cursor on the desired staff and select the Hide K.S. On Current Staff Only menu item.
