Keyboard shortcut for adding spoiler tags

I’d like to suggest a keyboard shortcut for wrapping the highlighted text in spoiler tags. I use spoiler tags fairly regularly, so being able to use a keyboard shortcut instead of typing the tags or selecting from the menu using the mouse would be a huge time save. I’m not sure what shortcut would make sense though. Maybe Ctrl + Shift + S?

Any thoughts on adding this keyboard shortcut?

I’m also curious how the Discourse team determines what keyboard shortcuts to add in general. Since I see shortcuts like Ctrl + Shift + 7, it seems like there’s plenty of opportunity to add more keyboard shortcuts.

Also, are keyboard shortcuts configurable at all, such as on the install level?
