A large collection of "tab" keys in Word

What's the use of this key when you have a TAB key in Word? It is generally located in the upper left corner of the keyboard, not very visible, I have not been how to pay attention. I've seen the use of shortcut keys for Word before, because there are too many, so I don't remember.

Know recently to use a table, from top to bottom input, with the mouse to switch speed is very slow, each fill in a blank, to the hand from the keyboard to the mouse point next to a blank, very slow, and use soft.

Later I asked my colleague if I could set the input in the software to automatically change lines, but he said he didn't know when you were going to lose. If you want to move down to another space, pressing the TAB key will solve the problem.

I unlike, the news to the special help me to input a clerk, the result she said, I know ah, I now is the use of this.

Oh, it seems that I am behind. I just don't know. They are small clerks know a lot of switch keys, it seems that the key on the keyboard to switch quickly or hard back, a lot faster.

At least I think the TAB key is useful when you enter a form to wrap in the software. Not only is it common in Word, but it can be used in all the software forms for wrapping.
