Keyboard keys turned into "shift"

greg90 - Oct 8, 2015 at 08:50 PM

I have touched a lot of keys while cleaning the dust of my keyboard and I just noticed that the keys "b" "n" "m" "," and "." actually activate the shift function. I have seen this with the keyboard viewer, tried to change the keyboard language, tried to reset a few parameters, restarted the computer but so far nothing worked...
I guess the keys are not broken otherwise they would not activate another function but I don't see where to find the problem!!!
PLEASE Help!!!

thank you!!
