Keyboard shortcut for blockquoting?

Is there any chance of introducing (or am I totally missing?!) an option to highlight text that you are entering in a comment and then blockquote it? I know if there’s a preceding comment you can highlight it and press r to turn it into a quote, but I’m more wanting to put a quote in the initially comment (often when adding an issue there’s a user comment I want to capture as a quote)

Ctrl-B and Ctrl-I work but for blockquote there doesn’t seem to be a shortcut.

As an aside for Discourse I see it mentions Ctrl-Shift-9 to do this but it doesn’t actually seem to do anything! Ctrl-Shift-C for code works OK though So it turns out that Bitwarden was blocking that shortcut!
