I'm aware of how you can go into the keyboard shortcuts and provide any listed functionality with your own customized keyboard shortcut,
but what if you want to make a global change to a key...OPTION in this case. You can hold OPTION (on a Mac) and this allows
you to select only the video or audio of a linked clip without having to shut off the linking button. Can you change this function so it
happens when you hold the "U" key for instance, instead of the OPTION/ALT key? I don't see "Select Video or Audio" as one of
the listed Premiere Pro functions so does that mean this type of remapping is not possible? Thank you for any input.
