How to reverse direction of moving with pressed mousewheel button on map?

[Ceres]

Hello!

As alternative to the arrows, I more often use the mouse to move around the map by pressing and holding the mousewheel button and moving the mouse around. Currently, when I move the mouse upwards, the map scrolls downwards (similar for left/right etc.). Personally, I find this a bit "unnatural" (knowing that other users like this, also in usual office apps) and wonder if this can be reversed in some settings file. Or maybe it could be possible to add a key shortcut to reverse this? Oh, maybe there could be even a key shortcut to increase/decrease the amount of field being moved, i.e. in smaller or larger steps?

Thanks for sharing your knowledge about this.
