In insert mode, type the first couple of characters of a word, then press:
- Ctrl-N to insert the next matching word; or
- Ctrl-P to insert the previous matching word.
This is particularly useful when entering the names of variables in a program.
'complete' option controls where the keywords are searched (include files, tag files, buffers, and more).
'completeopt' option controls how the completion occurs (for example, whether a menu is shown).

- File completion: <C-X><C-F>
- Line completion: <C-X><C-L>
- Omni completion: <C-X><C-O>
If you have several words you would like to complete, you can use Ctrl-X Ctrl-P to extend the match. For example, suppose a line exists in your file:
$res = mysql_query($q) or die(mysql_error());
You want to type the line:
$result = mysql_query($q) or die(mysql_error());
$result = my
Keep pressing Ctrl-P until you get to mysql_query.
Then pressing Ctrl-X Ctrl-P will give:
$result = mysql_query($q
