Can't move camera using hotkeys on campaign map

Hey all!

I'cant use the hotkeys to move the camera on the campaign map, even the middle boutton of my mouse is not working.
My little brother came and push all the buttons of my keyboard; he maybe(probably!) desactivate it. But it's strange, because the others hotkey are working.
I must click on the radar map to move it and it is not practical...

I delete the folder in Appdata, reinstall the game, but in fact, it concern only my current save; I create a new one and all is ok.
But i don't want to restart a new campaign ><.

Someone have an idea of the possible manipulation to do to restore the control of the camera ?

(Sorry if my english is not correct, I'm French ^^")

Many of the hotkeys don't work. Will they be fixed? I don't know.

Ok, thx for the answer
