Owen, this was very helpful for some related questions, but I'm still not sure I understand for to define an element for a specific Koha page. For example, on the query wiki are these 3 examples: $("#memberentry_contact label[for='phone']").html("Primary Phone :"); $("#memberentry_messaging_prefs tr:contains('Upcoming Events')").empty(); $("#patron-messaging-prefs tr:contains('Upcoming Events')").empty(); These seem to be "Koha" elements rather than standard DOM elements. How would I know that, or am I missing something?

I'm not sure that I see that FireBug reveals 'opac-main-search' as part of any element's description in the OPAC. I wrote some about that for KohaCon 2009.
