Comment 45 for bug 41427

I was hit by this on 12.04 with Xfce (not sure if this belongs in a different bug), which doesn't seem to have any way to permanently disable from its config panel. Took we a while to figure out how to type at all in order to search for what I'd done -- and it was very difficult to hold the key exactly the length required (which was very long, much more than I'd expect would be required for someone who's having trouble with accidental adjacent keypresses), but not long enough to trigger autorepeat (I have the repeat delay set to the 250 ms that used to be standard, but even the now-for-some-reason-default 500 ms or so would probably be too short compared to the very long initial delay).

It also seems perverse that a feature that requires you to hold keys down for a long time as part of normal use, would be disabled by holding a certain key down for a long time.

I agree with those that say it should be disabled by default -- especially if it's not going to even ask for confirmation via a dialog box.
