Dynamic Fireworks Selection

Probably a noob question...

Been doing a lot of Dreamweaver extensions, and one of them sends info to Fireworks to generate a new image dynamically (based on user selectedvariables).

I figured out how to get the code through the History window and now I can use

FWLaunch.execJsInFireworks('fw.getDocumentDOM().moveSelectionBy({x:10,y:10}, false, false);')

Which works great - assuming I have something selected. How do I select an element dynamically via dreamweaver?

Say I have a Text Box labeled "TextBox1", how can I tell it to do this (with the right syntax):

FWLaunch.execJsInFireworks('fw.getDocumentDOM().selectElement(TextBox1);');

(Since selectElement isn't a valid funtion)
