Changing Notes chromatics and octaves

You change notes chromatically using - and = key. You can change the octave using the _ (underscore) and + (plus) keys. The mnemonic device for this is 'plus and minus' for raising and lowering pitches. You can change the enharmonic spelling of the note using the Shift+E (mnemonic: E for enharmonic - get it?). And Shift+F gives you a courtesy, or cautionary, accidental (mnemonic - F comes after E).
