I have macbook pro early 2011 and i have upgraded the os to mountain lion. Today key 'p' is doing strange things. p0p0p0 --/p0p0 -/-/p0 \p0
above things came when i am pressing 'p' key, onscreen it shows volume notification and reduces the volume. so now its working like F11 key and printing garbage things.
How can i trouble shoot this p key problem? Note: in this post i have used p using copy paste.
