...is there some other library or workaround to solve my problems? Here is some code I used to play around with these functions: X11(type="Xlib"); keydown = function(key) { cat("Got key: ",key); lastkey <<- key } setGraphicsEventHandlers(onKeybd = keydown); plot(c(0,0)); getGraphicsEvent(); Well, I think it's great that getGraphicsEvent exists at all, and want to salute Duncan Murdoch who is listed as the author. I hope I may have helped by describing some new possible uses for these functions. Thank you, Frederick
