I have dropped some water on my keyboard and only one key is not working which is the DOWN key. I want now to use some other keys such as right Alt or menu key between right-Alt and right-Ctrl keys as I do not use them very often. I have open the us file in ...xkb/sybmols/us file, however, I am very confused and could not find the Up, Down, Left and Right keys. Can anyone help me to remap the Down key to the menu key on the keyboard? Thanks
