CMD + W doesn't work anymore on macOS Mojave After installing the .dotfiles on my new Macbook (Mojave) the keyboard combination CMD + W to close tabs or windows stopped working system wide.

I found out that when I press fn + CMD + W it works. But this is not my desired solution. 

Any suggestions on how I can get CMD + W to close tabs or windows?
Resolved by installing the dotfiles again. Still don't know what caused the problem…
