I've tried to create my own user command:
1 -adds a volume key frame at 0 decibels
2 - skips fw 15 frames
3- adds volume keyframe at -20 decibels
4- skips fw 15 frames
5- adds volume keyframe at -20 decibels
6 - skips fw 15 frames
7 - adds final audio keyframe at 0 decibels
The idea is to create a dip in volume as can be seen here (https://youtu.be/C2KAhbt9KKs?t=1143)
Unfortunately, the skip forward many times shortcut is not working. On my machine it's set to the default [SHIFT+Right]. I can see it creates the first keyframe, then creates a second keyframe in the same place at -20, then finally creates a keyframe again in the same place at 0. So it runs through the commands except the "skip frames" command.
If I press the actual keyboard shortcut [SHIFT+Right] it does work on its own. But as a part of the "Add user command" it does not work.

I'm attaching a photo of the command list. If you use this command list, I believe it will reproduce the issue. If I'm doing it wrong or If you'd like me to screen record the problem, please let me know. Thanks!
