Look in the language files all the text is in there:
If you look in English.lng towards the very end you'll find this:
if( $MenuType == 1 ) {
$menusep = ' | ';
$img['admin'] = $txt[2];
$img['delete'] = $txt[31];
$img['email'] = $txt[69];
$img['email_sm'] = $txt[69];
$img['help'] = $txt[119];
$img['home'] = $txt[103];
$img['im_config'] = $txt[323];
$img['im_delete'] = $txt[412];
and so on
To change the text find the corresponding item.
E.g. $img['home'] is the home text so look for $txt[103] near the beginning of the file and edit that.
Hope that helps
