Which is the longest key on the key board?

C is the answer to this question. It is the space bar that is the longest in the keyboard probably because it can be used often. It will not be too hard to type when you know that you can access the space bar with both hands. There are some recommended ways to type to work faster.

For example, the letters that are located on the left side of the keyboard will be sorted by the left hand while those that are on the right will also be sorted by the right hand. The space bar can be accessed by both sides. Some people even test their typing speed by timing themselves.
