ButtonNote
• ButtonNote is an option for buttons that determines what should be displayed in the status line of the current notebook window when the button is active and the cursor is placed on top of the button.
• By assigning a value to ButtonNote, you can provide a visual cue to indicate the function of the button. For example, in the Complete Characters palette, each button has the full name of the character as the setting for ButtonNote.
• With the default setting ButtonNote 
None, no text is displayed in the status line.
• Any expression can be specified as the setting for ButtonNote, though most windows will only allow a single character height to be displayed.
• ButtonNote can be used to display keyboard equivalents for buttons in a palette.
• See also: ButtonData, ButtonFunction, ButtonStyle.
