Sometimes I need to help a coworker and go at his desk and sometimes, rarely at least, I need to use his keyboard else it would be too long to tell him what to do.
The pain. I hit the keys, then double watch what I just entered since the signal that my fingers sends to my brain is: Error, feedback from keyboard is corrupted. Plz contact your administrator and tell him your keyboard is broken.
Then I go back to my desktop, use my keyboard, and enjoy the feeling of money well invested!
