    #{minimum_os}To get started with a set of mappings, try running the these commands:

        mkdir -p $HOME/.config/dome-key
        cat <<EOM > $HOME/.config/dome-key/mappings.dkmap
        map <Play> <Nop>

        mode <Play><Play> {
            map <Up> <Left>
            map <Play> <Space>
            map <Down> <Right>
        }
        EOM

    If `dome-key` is already running, load the new mappings:

        dome-key --reload-mappings
