Discuss the advantages of using keyboard over the mouse for improving work efficiency.

The main advantage is that your hands never have to leave the keys. Using a mouse, you have to grab the mouse, position it, click it, return your hand to the keyboard and find your home position.

With a mouse you have to locate the object on the screen and then click on it, this is not efficient and may slow down work speed. But if you use a keyboard you will only have to press a button and then the same task is done, this is more efficient and it will save time in work especially if you use applications such as Microsoft word or excel.
