I don't see how it exists at the moment. Here's an example.
You're in WoW Classic semi-afk eating a sandwich when a rogue pops out and kills your lead toon in a couple of hits. You hit your keybind to switch windows (again, Hotkeynet), swapping from WoW1 to WoW2. Now, at this point, how will your slave toons know to /assist the toon controlled by the WoW2 window?
The in-game macros for retail can easily be set to /focus Name and /assist focus, but there is no direct focus option in Classic. The example listed before simply shows how to broadcast keys within HKN based on the currently active and background windows, but that doesn't address the issue of the characters within the game not knowing that the currently active toon needs to be assisted (via /assist Name, to know what to target).
I don't just want to keep a setup where one toon is the leader, all of the macros reflect that, and if it dies then your team becomes useless. I'd like to be able to swap windows and have the characters be able to assist the newly active leader on-the-fly for wpvp. Blizz seems to have removed any sort of focus functionality, both the 2.0+ /focus and vanilla /script variants, and so I've been wondering how people can swap windows to a new lead and have their toons know how to assist the new leader. Maybe it's impossible since most people just use ISBoxer.
