I don't know how you can stand that...I had a pedal like that on my first digital and that is probably the reason why I ended up playing so much Baroque. Threw it away after a few tries. Then when I bought my present digital I had to get one with fixed pedals even if a stage piano would have been much more practical (I need to reassemble this one twice a year to move it).
Turn the pedal unit sideways and rest your left foot/leg on it. That'll stop the wretched thing running away. I do it all the time. You soon enough get used to the slightly odd angle of the right foot.
it doesn't... that's why I said don't try this at home...smarta$$
