Missing slash Key in Archlinux Install

Samsung Chronos 7 keyboard has the / key as secondary for the key Q. To use the key / in the Archlinux installation it is necessary to add a mapping like <Altgr> + q.

1. Detects a keycode from the key pressed on the keyboard.

root@archiso ~ # showkey
kb mode was UNICODE
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode  28 release
keycode  16 press
keycode  16 release

2. Decompress the map file

root@archiso ~ # gunzip /usr/share/kbd/keymaps/i386/qwerty/br-abnt2.map.gz

3. Edit the file using any text editor (here is Vim)

root@archiso ~ # vi /usr/share/kbd/keymaps/i386/qwerty/br-abnt2.map

4. Add the following to the file

altgr   keycode  16 = slash

5. Compress the file again

root@archiso ~ # gzip /usr/share/kbd/keymaps/i386/qwerty/br-abnt2.map

6. Load the new map file

root@archiso ~ # loadkeys br-abnt2
