Hi,
I tried to use this on my local installation and it does not work (show the icon but does not pop). I saw it in action on at least one other wiki and even here it does not consistently work. I like the idea and it's more elegant than footnotes in a form, but if is not documented on how to make it work properly. (sorry, I tought it did not work here, but it does not work in preview only).
It does work in preview as well [0] but if for some reason you have an extension that use JS differently as shown here [1] then JS execution is blocked which is a prerequisite for [0] being successful.
As in [1], find the malefactor, correct the JS, and you should be able to see that it works in [0] as well.

The reason for the mentioned "Error: Unknown dependency: jquery.delayedBind" as shown in [1] is mostly likely caused by the WikiEditor extension [2] (on this wiki).
I know nothing about JS so I do not want to mess into the files. I think that I will look into creating a template to do the same thing using some css.
There is still some job to do on my templates and forms, but I should soon have all what is needed to make a website to list japanese temples, then when I have enough entry, I can add shrine, castle, gardens.
After that, I will wait for a new release of semantic bundle and try to figure out if it's worth making a live website.
