Linux Vim basic Operation method _linux

I've recently been using Ubuntu11.04 to learn Unix before, but Ubuntu11.04 X window does not perform well under VMware7.1.4. It doesn't matter, first put the basis of the command line to say.
Ubuntu VI is also not good to use, a vim used to learn, a simple record of its basic operations, spare, to provide you with a book "Unix Practical Course (5th Edition)"
Command mode switch to text input mode:

Key	Function
I	Enter text at the left of the cursor
I	Enter text at the beginning of the current line
A	Enter text on the right side of the cursor

Regardless of which shortcut key is used to enter this mode, in insert mode, it is inserted before the cursor.

A detailed explanation of the commands can be used in vim: Help [command] to query online assistance.
