From Wikipedia:
Touch typing is typing without using the sense of sight to find the keys. Specifically, a touch typist will know their location through muscle memory. Touch typing involves placing the eight fingers in a horizontal row along the middle of the keyboard (the home row) and has them reach for other keys.
The most common other form of typing is “hunt and peck” (or two-fingered typing) which is slower than touch typing because, instead of relying on the memorized position of keys, the typist is required to find each key by sight and move fingers a greater distance.
So this is why I am a slow typer… I was pressing 0 with the blue finger, all along.
