I am trying to add some additional fields to the Link popup window which is opened when a user clicks "Hyperlink" in a rich text editor.
I would (ideally) like to replace Link.aspx in Editors\Views\Popups\Link
with my own extendedLink.aspx page.
I have been looking at the <extensions>
node in the config file (and numerous examples around the web):
<ext:editurls />
<ext:listdefinitions />
<ext:taskbars />
<ext:commands />
<ext:commandextensions/>
<ext:contextmenus/>
<ext:lists />
<ext:tabpages>
None of these seem like an obvious place to put an extension to an existing popup window.
Am I going about this all wrong? Should I be using JavaScript to extend the Hyperlink button, turn off the existing popup, and then provide my own?
Should I remove the button entirely and replace it with one that's identical?
