There’s the problem! Your original post said forefinger! Not thumb! LOL! My hand must be different, I’ve been all over that darn throttle handle, thumb, forefinger, little finger, middle finger??( 
). So far haven’t found the sweet spot. I’m rear persistent tho, I’ll keep trying. I actually know what the TOGA screen should look like when activated, but with about 35 hours on the Hobbs meter, I still don’t know what I don’t know… Thanks so much for trying to help, the pictures are great!
