Hello. What do you want to achieve? Im not a script guru but if your goal is to play a file in a list and only this, you can do a simple "Select index" and then "cut" or "play" script with autonext in the list disabled. And if you want sometime to play 2 continouous files you can enable "Autonext" with a shortcut and disable it after.This way you can have all the time all files in the list enabled and play whatever you want. This is the way i do it
Or if you want to do this in a more complicated way for example to play a next file that is not after the active file, maybe you can write a script that checks the active file and decides what to do next
