Key, Chords and Modes drop downs ... 
If you click in a select box for key, chord or scale it displays correct notes and fingering.If you double click without moving the mouse cursor arrow, the textbox will become highlighted and then you can use the up and down arrows of the keyboard (the one you type on) to change key, chord and scale variations. Modes will only come into effect when clicked on and will use whatever key you select. When you use modes (scales)... the chord type select box is irrelevant. 
(although any modes setting in the display boxes is actually irrelevant when clicking on notes and finding chord names... if you click in some scale then remove a note or two, the chords you see will be based on that scale).

  P5: G

 ■ C Diminished
  Root: C
  m3: E♭
  ♭5: G♭

 ■ C Augmented
  Root: C
  M3: E
  ♯5: G♯

             ○ Cdom7: C - E - G - B♭ (M3, P5, m7)

             ○ Cmin7: C - E♭ - G - B♭ (m3, P5, m7)
             ○ Cm/M7: C - E♭ - G - B (m3, P5, M7)

The Symbolism of the Piano in The Piano - The Symbolism of the Piano in The Piano         The piano has been inextricably linked with the roles and expectations of women in British society since its advent in the mid 1700s to the late 1800s when rising standards of living made it more accessible to middle class society. Pianos were regarded as "secure icons of social distinction" 1 and a wife was viewed similarly as a possession of "privatization, success and respectability."2 Pianos were instrumental in both reinforcing gender roles and as delineators of class distinction thus perpetuating the class system....   [tags: Piano]
