Hope I made myself clear.
This is a really important thing to keep in mind when creating upgrades. Often buttons have multiple meanings on the originial remote and its really important to convey that on the functions sheet. When you don't have the remote in front of you its really hard to tell what the buttons are supposed to do. My personal favorite was when play was the same as uparrow, and stop was the same as downarrow.
Trying to figure that out from a file that I downloaded turned out to be a really big deal too!
