I've only now finally managed to get homm 5. I love to make maps and I'm trying to learn to use the map editor, but I've yet to figure out how to scroll the map. It doesn't have the handles to scroll up/down and left/right and I'm clueless how to zoom for example to the NW corner.

Help would be appreciated and apologies if someone's already asked this. I made a search but I didn't find anything about this.

Press down the middle mouse button and move the mouse, this will scroll the map, it's much easier than using the traditional sliders that one finds on some of the older map editors in my opinion.
