They return a modified copy of the XML. There's no way that I could find to also return a selection, or to trigger any keyboard shortcuts within Inkscape itself.

Essentially an extension is a black box with XML fed in at one end, and XML coming out at the other end. There's not really any interaction with Inkscape itself, other than as a source and sink for the XML.

Xav, you are right... but in theory it's possible to have some access to some features of Inkscape using the command line"verbs" system

Some extensions implement this feature (the export to synfig extension, if I'm not wrong)... but you have to code it. A better approach would if were just a module...I guess...
From time to time, this same topic is discussed here in the forum.

As Xav said the extension is called with the path of an xml file (and a list of selected items) and wrote a [modified] xml.

I don't see when you could pass a query to [the already running instance of] inkscape.

Unless your extension calls another [hidden] instance of inkscape which would be quite complicated imho

I'd be glad to hear more about interacting with inkscape from an extension.
