I am trying to get the “chars” or “keyCode” value when a key is pressed. So return which key was pressed.
I see the info[“event”] NSEvent but can’t get anywhere from there.
I tried to get an idea from the developer site to no avail.
Is there an example file or some other help.
Please. Thanks. jo

This should do it to catch keydowns in a glyph view
```
from mojo.events import addObserver

class testKeyDown:
    
    def __init__(self):
        
        addObserver(self, "keyDown", "keyDown")
        
    def keyDown(self, notification):
        event = notification["event"]
        print event.keyCode()
        print event.characters()
    
testKeyDown()
```
good luck!
