Consistently documenting keyboard shortcuts, Ctrl+Shift+C copy Spotify URI

[Phiz]

There's a hint popup about using Ctrl+Shift+C to copy a Spotify URI to the keyboard, but this isn't mentioned anywhere else in the UI (eg. the obvious choice of it being a window menu selection).

Help "keyboard shortcuts" gives a list (https://support.spotify.com/uk/using_spotify/search_play/keyboard-shortcuts/) which doesn't mention Ctrl+Shift+C, so I'm now confused if that's even a thing or equivalent to Ctrl+C or whatever?

These sort of "learn how to use the interface" queries should be plainly obvious and more (re)discoverable. Ambiguities about what user input is actually doing is bad UX design, Spotify can do better here.
