Hi,

Your '<Control-o>' is what Tk calls an event sequence [1].

Your event sequence does not specify any event type [2].

Some event sequences allow the event type to be omitted
for brevity. For example [3]:
  'x' is the same as '<KeyPress-x>'

However, I suspect that what you have might not be recognised.
Looking at working code I have here (without actually
testing what you have) I see that I have:
  '<Control-KeyPress-o>'

Maybe try that.
