So, this is somewhat related to (it turns out: mine ) previous topics:

The current problem I have is that because there is no sane solution for 1st topic (yet) and the 2nd is quite inconvenient - 5 key is close to 1-4 used to rate the answer, leading to quite often hitting the wrong key - I would like to suggest switching “Stop playback” from 5 to [esc] key:
it’s more separated = less chance to confuse it
[esc] is usually associated with cancelling some action, which would fit it better semantically.
Esc closes various dialogs, and I think it might get a bit confusing if it also served this purpose. I imagine this is a tweak you could make with an add-on for now however.
