Congrats on the kill!


You could set this up with mapped keys.
The Shift-1 through Shift-6 (or as many as you'd like).

Use a Keymap State Action.
Assign a hotkey for each boss.
On the press, it will disable the Keymaps for the other bosses.
And load the keymap for the current boss.

Something like:
Keymap State Action - Target: All Windows, Keymap: Trash & Heroics, State: Off
Keymap State Action - Target: All Windows, Keymap: VoA, State: On

If you wanted, you could even make this a round-robin effect.
Where each 'step' disables all of the other Keymaps, yet enables the next one.
Then include a Pop Up Text, to announce which Keymap is the active one.



Not sure on the communication between two machines.
I only play on one, myself.
