keyboard typing error on letter -p, -puts a dash before letter -p

[Keyboard destroyer]

I cleaned by keyboard with the com-puter turned on but without any -programs
o-pened now the keyboard letter -p (-p) puts a dash before the letter and the
dash -puts a -p (-p). I have reloaded the keyboard several times but this
does not fix it.
I am using Windows X_P home edition

What does this have to do with Word?

You probably have a short or some dirt under the keys between P and
- .
