Randy started this thread and so I decided to do a little digging. Unlike
computer keyboards years ago, today's modern computer keyboard uses open relays
which are part of a grid running under the entire keyboard. The position of
the keys on that grid determine which information reaches the computer or other
electronic device. The keys still travel within their respective zones but
when they make contact, it is to a grid which is, other than in relationship to
the position of the key, common to all of the controls in that block. To put
it simply, the introduction of liquid into the keyboard housing will create
many undesirable consequences. The keyboard designers like Logitek recommend
that if a keyboard is exposed to what they call "free liquid", it should be
disposed of immediately since it might, through the indeterminate nature of
possible unanticipated connections, cause serious damage to the CPU.
In English, if it gets wet, get rid of it.
