"swap" defines "source" and "that" unexpectedly

[Enyium]

File:

foo
bar
Baz

Do this:

• "pre file"
• "swap this with <bar>"
• "flash source" - Error: "No available source marks"
• "flash that" - Flashes both marks.

Is that intended? It's definitely unexpected for me.

Yes that is intended. Swapping A with B or swapping B with A gives the same result so there isn't really any source since they are all sources and destinations. I can't say that I really use the that mark with the swap action. We could of course make the first one source and the second one that. That might make it more useful?
@pokey Have you run into this?

[Enyium]

Both orders make for the same result, but since you mention them in different orders, your mind can also reference independently the first or last mark you mentioned with "swap" to use it for the next action. It's about the human intuition, not he editor result. It seems you would always be able to use "source and that" to achive the current behavior with "that".

I don't have a strong feeling either way. Could see source being useful here
