Summary irresponsibly on by default

My cat likes sleeping on my laptop (it's warm, obviously it's a cat bed). My laptop sits on my desk between keyboard and monitors, so when she lies down on the laptop and shuffles around (as cats do), her butt ends up pushing the keyboard around and pressing keys. I regularly wake up to a dialogue asking me if I want to enable carat browsing (whatever that is) . . .

. . . and having now looked it up (the trigger key is F7, right in the middle of the top row), I guess it could be worse - like waking up to a million help browser windows, or running out of disk space after a few days if the print screen key still triggered a screenshot automatically . . .
