<a name="line-137"></a><span class='hs-comment'>-- depends on the application. If you're using a terminal app, this is in</span>
<a name="line-138"></a><span class='hs-comment'>-- two parts:</span>
<a name="line-139"></a><span class='hs-comment'>--</span>
<a name="line-140"></a><span class='hs-comment'>-- * The console app must send a ^G (bell). In bash, a helpful trick is</span>

<a name="line-143"></a><span class='hs-comment'>-- * The terminal must convert the bell into UrgencyHint.</span>
<a name="line-144"></a><span class='hs-comment'>--</span>
<a name="line-145"></a><span class='hs-comment'>-- 2. XMonad must be configured to notice UrgencyHints. If you've added</span>

<a name="line-147"></a><span class='hs-comment'>--</span>
