Thanks man that was really helpfull 
Heres the tsi for the cue point filter on/off… load the file, make sure its allocated to the S4 and then press either shift and the appropriate cue point. I often use it to swap decks A/B to drop new basslines
I didn’t review it, only quickly but actually Rainer’s method for your specific case would be wrong if you use the copy mode.
In the original example, he duplicates the browse mode (as far as I remember) with a modifier, but not the copy mode, ie, meaning the tutorial is not 100% correct. No real issue because having a cue pressed on or off is not a big deal in the end.
In your case having a filter on or off while using the copy mode may not be recommended I think.
No, I don’t need a way to duplicate the copy mode and all the buttons related behaviour, it’s an issue causing me headaches and didn’t find a solution.
