As I said, you may need to change the F11 for GoldWave and/or Playroom.
Not all input gestures are assignable, and if the one for NVDA Remote happens to be a fixed one, then look to the other(s).
There are a finite number of keyboard shortcut combinations, and the more add-ons and/or other software that's running the more likely a collision will occur. If you have two that collide where neither can be changed, then you will need to disable the one you do not need at the moment in Add-Ons manager.

The depths of denial one can be pushed to by outside forces of disapproval can make you not even recognize yourself to yourself.
