AVA208: Is there a source on the Internet for all of the toe-toe, heel/heel scale patterns?

This question was sent by Jane. She writes: Is there a source on the Internet for all of the toe-toe, heel/heel scale patterns? I am playing 15-20 hours per week in preparation for some private lessons in Paris this summer. I am an accomplished musician, but my pedal technique has become lazy over time. Working it back into shape as I am playing repertoire such as the Guilmant, op. 42 which has very demanding pedal passages. Thank you for your inspiration! Jane
