Automatic event selection

When user wants to set an event, he should be able to press a 'capture' button, and then press a key or send noteon etc, so that harmonySEQ would set event's parameters according to what was triggered. Something like guessing the event according to the next one triggered.
For example, user adds a new event, then he clicks 'auto' or 'guess' (the naming is still to be chosen), and presses the K key - harmonySEQ should automatically fill in the event data: type - keyboard, key - K.
