I want to Reread a file in VI


I would like to write a script that would reread from hard disk,  a file that I AM CURRENTLY EDITING IN VI.

The problem is:  How do I get VI to easyly reread the copy of the file on the hard drive without closing the file and reopening it ?

Example:

1)   I am writing a script named "myscript".

2)   I want to insert an example of a command with the CORRECT SINTAX :)
     

example:
=================================
The syntax of the if...then control structure is

   if test-command
     then
         commands
   fi
==================================



3) Now in the VI editor session I am in I want to read off the hard disk the new file contents  so I can just  change the "test-command" and the "commands" veriable.

What I am looking for is a nice helping aid in case I get a job shell scripting and have problems with the syntax.   People look at you funny if you paste in all the examples !!!
