@Daniel > The reason the post was closed is while you can remap that function, it requires tinkering around in a file which is not generally accessible to the end user, and as such, we can not provide instruction on doing so. The reason it's not accessible is the layout and mapping is provided in such a way as to match functions of the player as closely as possible. Providing users with a method to change these functions would create the possibility of users accidentally modifying core functions and requiring additional support which is costly and time consuming. I hope you understand.
