What are the most important keys in a computer keyboard?

Answer: numners smart one

Answer: They let you quickly type numbers (if the "numlock" key is on), or have an alternative access to arrow keys (if "numlock" is off). With practice, typing numbers here is faster than using the numbers at the top. With respect to arrows, it is especially interesting that some games allow the use of "diagonal arrows". For example, the "home" key might be redefined to move to the upper left, to reflect its position between the up and left arrows.
