I'm pretty certain this is not possible in the general case. One of my persistent pet peeves with GUI toolkits is that it is not possible to insert your own arbitrary events into the toolkit and get the toolkit to do *exactly* what it would have done if it had received that event. While I believe Tk has a "post event" method, it only posts user events, I do not think you can post system events. This would completely change the testability and programmability of all GUI toolkits, radically improving them for agile development... but that's another rant. Meanwhile, you've got two options, depending on what you are trying to do, what platform you are on, and whether you control the target system. You could actually re-map the keyboard, which all major OSs support, although that may be too drastic. You could register two event handlers to the same handling function, so that both "p" and "t" go to the same place. Finally, if you're working with a Text widget, and you want a "t" to come out when users press "p", what you do is capture the "p" event (either by registering "p" or "<Key>"), insert a "t" at the INSERT point, move the INSERT event forward if you have to, and then cancel the key event by returning "break". Basically, you are implementing the keypress handler manually. (To fully emulate the keypress, consider if you want to emulate the behavior where a keypress destroys the highlighted range, in which case you need to look at SEL too.) This is a pain, and there are a lot of cases to cover, but it can be done. -- http://mail.python.org/mailman/listinfo/python-list
