Hey Frederik,

Is there anyway to find out what has been selected by mouse using any observer. I want to be able to show mark glyphs only on selected anchor simply because it’s faster to render.

Thank you as always :)

there is “Glyph.selection.Changed” notification

small example
also don’t forget to remove the observer when your are done…
```
class SelectionObsever(object):
    
    def __init__(self):
        self.g = CurrentGlyph()
        self.g.addObserver(self, "selectionChanged", "Glyph.selectionChanged")
    
    def selectionChanged(self, notification):
        glyph = notification.object
        for anchor in glyph.anchors:
            print anchor.selected
        
SelectionObsever()
```
