It was reported to Alacritty that when pressing Control + Shift + 7 on Norwegian keyboard no characters are getting received. For the reference this keyboard has / on Shift + 7, so it assumed that it should act like Shift + Control + 7 on us keyboard (I mean it should gets / like it gets& when on us). Shift + 7 works just fine on this keyboard (sends / and getting Slash virtual_keycode).

alacritty bug for the reference alacritty/alacritty#2850
