VIM Completion:

The most common method of completion should be ctrl-n and ctrl-p complement. They look in the current buffer, in other buffers, and in the header files contained in the current file, to find words that begin with the keyword before the cursor. The intelligent complement cannot complement the local variables, while the ctrl-n and ctrl-p complement can be well qualified

Ctrl-p General meaning is upward, so ctrl-p complement is looking up to complete, and ctrl-n is looking down for completion, The speed of completion can be accelerated by using different shortcut keys on different occasions.

Other methods of completion in Vim include:

Complete line completion                        ctrl-x Ctrl-l based on the key word in the current        file to completethe control-X-Ctrl-n based on the dictionary completion of the                    CTRL-X Ctrl-k based on the synonym dictionary complete              Ctrl-X Ctrl-T complements thekey word in the header file          Ctrl-X Ctrl-I based on the label completion                    CTRL-X Ctrl-full file name                      Ctrl -X-Ctrl-f complement macro definition                      CTRL-Ctrl-D complete vim command                     CTRL-X Ctrl-v user-defined completion method              CTRL -X Ctrl-u spelling suggestion                        CTRL-X ctrl-s

You can set these two variables in VIMRC, for example:

2"<C-X><C-O> "

Now you can use tab to complete the completion, like in the shell, the convenience of a lot!
