Okay, that was not the full on seizure, right? That was the bit before the seizure, known as the aura. The actual seizure, in my case, involves falling on the floor, frothing at the mouth, and usually ends up with me losing a fight with a neighbouring item of furniture. This is not conducive to fast or accurate typing. Some people's epileptic fits are a lot like the description; YMMV.
Here is a site explaining seizures, and this site has some good general info on epilepsy.
