Check or uncheck all :
<input type=checkbox onclick="checkSongs(this.form,this.checked)">
Uncheck all :
<input type=button onclick="checkSongs(this.form,false)" value=GO>
----------== other way ==--------
<form name="songsForm".... blah ....>
<p>Pre-selection :
all <input type=radio name="presel" onclick="wichSongs()">
some <input type=radio name="presel" onclick="wichSongs()">
any <input type=radio name="presel" onclick="wichSongs()">
<p class=sg><input type=checkbox name="SearchAdd_1" value="0"> Title 1
<p class=sg><input type=checkbox name="SearchAdd_2" value="0"> Title 2
<p class=sg><input type=checkbox name="SearchAdd_3" value="0"> Title 3
....
<p class=sg><input type=checkbox name="SearchAdd_20" value="0"> Title 20
