HoMM3 HD is a mod (add-on) for the game Heroes of Might and Magic 3.

Honestly, I don't understand what we're talking about.
1. Why would I cut all this out?
2. I have never observed anything like this during testing (including after reading this report).

Ctrl + down arrow - this function is useful, but I was confused when I needed to detach 5 units from 40 gnolls for another hero for a battle in the dungeon (all troops were transferred, and then everything had to be returned and done again).

I can easily revert to the old functions, and assign the new one to Alt, but I don't really want to, I don't see anything terribly critical in their absence. I've been using version 3.0 for so long that I've even forgotten about their existence.
All the other advantages of version 3 already more than compensate for this, if you can call it a drawback. Is it really necessary to use them so often? Does their absence make the game impossible? Then the original Heroes should be buried, because it lacks not only these functions.
