Why don't my fingers work?

I've been taking piano lessons longer than you have and I know that piano and arrow keys are completely unrelated based on the fact that I am still very bad at random dodging and stuff like that. What helped for me on level 144 was practicing on a modified CCLP3.dat which put me right at the end of 144, and allowed me to try the toggle-button frog ending over and over again until I got it every single time.

That's exactly what I plan to do. I tried it already, but I didn't start far enough back -- my solution didn't work on the real level.
