Maki, I had to reject the other translation you did because that text was included into this one and therefore it is considered a double request, OK?
For this one I guess the last line is: " ...with the letter that will appear on the keyboard on the screen."

I mean the screen will show a keyboard to be used instead of the normal keyboard of the computer. Am I right?

yes, you right.... thank you....

I thought it was a keyboard with a screen above. I'm not sure...
But if mtea says you're right then I guess it is a keyboard shown on a screen.
What do you think? Should I change it or leave it like this?

na = on
zaslonu = screen
tipkovnice = of the keyboard
