and can modify `mpd_notification_preset` table, which will be the preset for the naughty notifications. Check [here](http://awesome.naquadah.org/doc/api/modules/naughty.html#notify) for the list of variables it can contain. Default definition:

    mpd_notification _preset = {
       title   = "Now playing",
       timeout = 6,
       text    = string.format("%s (%s) - %s\n%s", mpd_now.artist,
                 mpd_now.album, mpd_now.date, mpd_now.title)
    }

### output table

Variable | Meaning | Type
--- | --- | ---
`widget` | The textbox | `wibox.widget.textbox`
`notify` | The notification | function

You can control the widget with key bindings like these:

    -- MPD control
    awful.key({ altkey, "Control" }, "Up",
        function ()
            awful.util.spawn_with_shell("mpc toggle || ncmpcpp toggle || ncmpc toggle || pms toggle")
            mpdwidget.update()
        end),
    awful.key({ altkey, "Control" }, "Down",
        function ()
            awful.util.spawn_with_shell("mpc stop || ncmpcpp stop || ncmpc stop || pms stop")
            mpdwidget.update()
        end),
    awful.key({ altkey, "Control" }, "Left",
        function ()
            awful.util.spawn_with_shell("mpc prev || ncmpcpp prev || ncmpc prev || pms prev")
            mpdwidget.update()
        end),
    awful.key({ altkey, "Control" }, "Right",
        function ()
            awful.util.spawn_with_shell("mpc next || ncmpcpp next || ncmpc next || pms next")
            mpdwidget.update()
        end),

where `altkey = "Mod1"`.
