Hello, I want to able to mount partitions, but to do so I need to type something like

mount c d:\dosprogs

but I am not able to do so because the keyboard key responsible for "\" is not mapped. As many other keys. So I opened dosbox-0.74.conf and found that the last line deals with keyboard layout. It is set to "auto" which I presume it is the standard USA layout. My keyboard however is a mini brazilian keyboard and I do not know what I should put in place of "auto" (or even if that is the correct curse of action to be followed). So how should I proceed ?
