how do I get the function of the arrow keys back to moving to the next cell instead of moving the sheet up, down, right or left?

Without doing anything to the program to my knowledge, instead of the arrow keys moving up, down, right or left to the next cell, they move the entire sheet up, down, left or right one row or one column. I am also having problems with a delay in typing in information and often dropping the first one or two letters. How do I g it back to moving among cells and eliminate the delay?
