sorry, my aim is not limited to one particular program. Yes, many library can permit you to respond to keyboard event, however, what I want is a universal function. as long as a key is pressed, no matter where, my program can repond. I am quite strange with this topic. But according to my understanding, any event, keyboard event for example, once triggered, will be dilivered by keyboard driver to X system, and then any running program can either choose to respond or ignore. So my question can be translated to: how to make my program respond ? -- http://mail.python.org/mailman/listinfo/python-list
