Disabling the zoomed out map

[Ketsuppi]

Would it be possible to disable the zoomed out map or change the keybind for it? I'm going to try a challenge where using it is forbidden and I just know I'll accidentally hit enter out of muscle memory... Disabling the proper map would be nice too, but I don't think it'll be that much of a muscle memory thing as pressing enter.

An extra cool thing would be if it could be modified so that you could only use the zoomed out map when you're on a mountain tile, as you would see farther there naturally.
