Or a method comprising the steps of: catching and storing a key information (16) when a key is stroked; comparing directly key information (16) with a group of key informations; and moving cursor (14) back one space if key information (16) is the same as any one of the group of the key informations, so that unskilled keyboard operators can press one of many keys to move cursor (14) back one space with 100% accuracy, with ease and without using the backspace key or the cursor left key.
