Well I found out that when you pass window id to xev it does not trap keyboard presses per-sé. But there is another way... Anway the following is a quick hack (in python). It pretty much works except it also seems to trap mouse presses. I got the .wav file at http://www.soundjay.com/typewriter-sounds.html I tried using 'xset c' but it basically does nothing for me. My guess is that it does work it basically sends the a BELL to the console. --- 8< CUT HERE --------------------------------------------------- import sys import subprocess soundfile = 'typewriter-key-1.wav' def main(): window_id = sys.argv[1] cmd = ['xev', '-id', window_id] p1 = subprocess.Popen(cmd, stdout=subprocess.PIPE) while True: line = p1.stdout.readline() if line.find('atom 0x14d') > -1: subprocess.Popen(['aplay', soundfile], stderr=open('/dev/null', 'w')) if __name__ == '__main__': main()
