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

A very useful feature has appeared in the game – by pressing Alt + left mouse button, the distance in movement points from the hero to a specified point is displayed, along with the remaining movement points at the end of the route. This significantly saves time for those who count squares and eliminates errors for those who rely on visual estimation. It would be great to add something similar to the mod.
