I don't imagine that a moving a list component around is the correct choice here, but it could probably be done effectively with a simple popup menu.

Example:
First, add a dataset custom property to the text area and populate it in some way, so it has a column called username.

Then, use the following script on the text area's mousePressed event to generate the popup when the '@' key is pressed:

if event.shiftDown and event.keyCode == event.VK_2:
	from java.awt.event import MouseEvent
	userData = event.source.userData
	userNames = list(userData.getColumnAsList(userData.getColumnIndex('username')))
	innerTextArea = event.source.viewport.view
	characterBounds = innerTextArea.modelToView2D(innerTextArea.caretPosition)
	mouseEvent = MouseEvent(
		innerTextArea,
		MouseEvent.MOUSE_CLICKED,
		system.date.toMillis(system.date.now()),
		0,
		int(characterBounds.x),
		int(characterBounds.y),
		1,
		False)
	
	def insertName(name):
		return lambda typeName: innerTextArea.insert(name, innerTextArea.caretPosition)
	
	menu = system.gui.createPopupMenu(userNames, [insertName(name) for name in userNames])
	menu.show(mouseEvent, int(characterBounds.x), int(characterBounds.y))
