Hi,
The [at]/apostrophe key has come off my keyboard, and the "key" is stuck down, so whatever application I am using on the laptop, a load of apostrophes are typed. I find that poking a biro down there stops it for a short period of time, but then it comes back again, and a load of apostrophes are typed, which doesn`t help when logging onto something.

I should really get the whole keyboard replaced, but is there a way of disabling a certain key, or disabling the whole keyboard and using an external one. (without physically taking the machine apart) ?
