Is there a keyboard shortcut / key modifier for adding links to the Reading List from Mail? You can hold ⌘ to open the link in the background, but that seems to be about it.
In Safari, you can ⇧-click links to add them to the Reading List. Does such a shortcut exist in Mail? I'm aware of the
Add to Reading List command available in the context menu; I just find it more cumbersome than I'd like, especially for newsletters such as StackExchange's, which are essentially a collection of links.
