This is a pattern I'd like to use myself and see more commonly—the context menu as a shortcut but not the only method makes a lot of sense as a balance between the average user and power users.

The only downside I see is that you're losing the browser's native context menu, but this is solved by behaviors like in Helium where `Shift+RightClick` forces the native menu[^1]. I'm not sure which other browsers if any implement that, however.
