howto change change yen character to backslash using xkb

[niya levi via arch-general <arch-general@xxxxxxxxxxxxx>]

hi everyone

i have installed arch with lxde ,

the keyboard is setup all the keys are setup except one the backslash key,

in thunderbird and openoffice a backslash char is displayed

but in the lxterminal and geany(ide editor) it displayes as a yen char,

i added Option "XKbOptions" "yen:backslash"

to /etc/X11/xorg.conf.d/00-keyboard.conf

but no change,

is the line i added to 00-keyboard.conf incorrect ?

i understand that the console is not affected by xorg so i'm also
looking for a solution there as well.
