With this kind of question, I usually start by asking where the code
does something similar to what I want. Teleporting via the map dialog
would seem to do it exactly, so I'd begin by looking at what happens
when you click "teleport" there. The easiest way to find that code is
to find the map UI file by searching for a visible string in the UI
descriptions in indra/newview/skins/xui/en-us. "Copy slurl to
clipboard" looks like a pretty unique string.

When you find that file, look for two things. First, the name of the
file. Somewhere in the code there will be a call to buildFloater()
that takes the filename as an argument. Searching for this should get
you to the right file. Also, inside the UI description file, look for
the "Teleport" string. The element that identifies the label attribute
(the visible part) will also have a name attribute, which is used for
identifying that button in code. Search for that name in the source
file that builds up that floater.

>From there, you should see code that sets up a callback for when the
teleport button is clicked. All you have to do now is set a breakpoint
on the callback function and follow through in the debugger. That
should put you right on top of the most current location teleport
logic.
