I believe any two posts linking to the same URL are treated as a cross-post, and that is discovered at instance-level. There's nothing more to it than creating two posts in different communities with the same link.

ETA: But to answer your question directly, there's no support for doing that as a single action with Jerboa yet.

src: https://github.com/LemmyNet/lemmy/blob/63d3759c481ff2d7594d391ae86e881e2aeca56d/crates/api_common/src/post.rs#L61

The setting is tied to your instance account, because the backend delivers the results with the specified sorting. If you change it via the browser, it should be reflected in Jerboa.

You mean a version later than 0.0.34alpha? Sorry, maybe I'm blind, I can't find it. Could you post the direct link?

I think it's funny. Also, while just researching to debunk the common "Lemmings committin mass suicide misconception", I came across these additional gems:

In 1532, the geographer Jacob Ziegler of Bavaria proposed the theory that the creatures fell out of the sky during stormy weather and then died suddenly when the grass grew in spring. This description was contradicted by natural historian Ole Worm, who accepted that lemmings could fall out of the sky, but claimed that they had been brought over by the wind rather than created by spontaneous generation.
[...]
Another myth may have roots in the fiercely aggressive nature of lemmings during population booms, and the corresponding leftovers of predatory frenzies: lemmings do not explode.
