The only possible way to close computer terminals is to click the mouse on the red square button. How can I close it with a keyboard command? It does not need to be a mod, it can be any other way.
I am on PC (but I think other platforms info may help other people too, but I can only check on PC), and so, any mods are welcome too.
Just as information, there is a console command CloseAllMenus (short: cam) that is capable of closing the terminal; though I am not sure how it can help concerning a hot key bind.
