sync * specifically syncs applets on the driver's page. Anything else would
be a nightmare in general. If you want to do it programmatically, I suggest
having your JavaScript get the property "appletInfo.registry" and from that
discern the FULL name of that popup applet. Give the popup applet a name
extension that the referring page can identify -- a random set of digits,
perhaps. You don't want to send this to the wrong popup in case the user has
two Protopedia pages up (which is a real possibility, of course).

Then use that FULL name in the sync. It looks something like this:

jmolAppletXXX__2923827392370230236823__

By giving that EXACT id, Jmol will send the message to that applet.

Alternatively, after the popup opens, an elegant way to do this would be to
have the created applet send back to the calling applet its id:


jmolApplet(.....,'[state scripts here];myID =
getProperty("appletInfo","fullName");jsCall = "opener.jmolScript(\'popupID =
\\"" + myID + "\\" \')"; javaScript @jsCall'

I think that's the right number of escapes there!  Text surrounded by single
quote needs \' inside...jmol command jsCall = "..." + myID + "..."  needs to
end up in Jmol as

  jsCall = "opener.jmolScript('popupID = \"" + myID + "\" ')";

so in the original we have to escape \ or it will be read as \" and change
to " by the initial javaScript processing. Gotta love it.

The "opener.jmolScript" is a simple way to direct the message to the applet
on the page that opened the popup without knowing its applet id.
