The Husband has a keyboard like that, sole survivor of one of his first computer purchases: it has many, many more function keys than I will ever recognize, the action is mechanical, and if anyone tried to break in to the house he would need only to drop it on their foot to dissuade them. He adores it, although truthfully he only goes back to the Medusa-workstation if there's something wrong with the server.

So, does the clack switch off?
