The nudge keys are not working. Specifically, the arrow keys and the page up/down keys for moving the selected objects by the grid quantum. When I press the right arrow, for example, I get an alert that says:
SyntaxError: Expected an identifier but found 'Right' instead
line 1
1: >> Nudge Right

I imagine that these functions are implemented with a script, but even so why is this script failing?

Thanks for making v4! FYI, I've got a file with over 5K objects. V3.2 loads it in about 29.5 seconds. V4 loads it in about 3.2 seconds. Wonderful!
