The scene is an imaginary tech support transaction…
user: This web site keeps making my browser quit!
support: Can you tell me exactly what happens?
user: Well, I went to the site, and it was full of good information, and it said ‘PRESS CONTROL-D TO BOOKMARK US!”
support: And what did you do?
user: I held down the Control Key, and then pressed the D key…
support: And what happened?
user: The browser quit!
support: Hmmm, what browser are you using?
