By pressing "Esc"+i key.

There are several commands that put the VI editor into 
insert mode. The most commonly used commands to get into 
insert mode are a and i.

this question should bhave been for many same words that 
appear many times, for this press escape to go to command 
line, then type
:%s/old_word/new_word/g
g for global

I guess both do the same task..! in the sense :wq,:x and ZZ
are used to save the changes of edited to storage and quit..
but to jot down the difference a foolish one.. :wq and :x
requires <enter> key to be pressed to fire this commands
where as ZZ works as a shortcut (hot) key.. it some what
like for prior commands we are requesting Vi to do the work
and later command we are telling/commanding

vi filename

In the vi Press 'Esc' and ':' then Type 'shell'
And you can go to shell and do different commands.
To return to vi editor type 'exit' in shell prompt.

to append file1 to file2. first open file1 in vi editor
using vi file1 command. then to append file1 to file 2 just
use the following command.

:w>>file2 so file 1 will be appended to file 2
