Yes, I have searched the library, but not really had any luck.
There are some nodes which claim to do it, but I think are way too old.
I am looking for a node which will see keys pressed on the keyboard and send the result out as a message identifying the key pressed.
(Ideally I want to see a specific - variable as needed - key. But that is easy to get around with a
switch node downstream from the node if it doesn't internally allow that.)
