+COMPLETING IN SOURCE CODE
+
+Source code files are well structured. That makes it possible to do
+completion in an intelligent way. In Vim this is called Omni completion. In
+some other editors it's called intellisense, but that is a trademark.
+
+The key to Omni completion is CTRL-X CTRL-O. Obviously the O stands for Omni
+here, so that you can remember it easier. Let's use an example for editing C
+source:
+
+ { ~
+ struct foo *p; ~
+ p-> ~
+
+The cursor is after "p->". Now type CTRL-X CTRL-O. Vim will offer you a list
+of alternatives, which are the items that "struct foo" contains. That is
+quite different from using CTRL-P, which would complete any word, while only
+members of "struct foo" are valid here.
+
+For Omni completion to work you may need to do some setup. For C code you
+need to create a tags file and set the 'tags' option. That is explained
+|ft-c-omni|. For other filetypes you may need to do something similar, look
+below |compl-omni-filetypes|. It only works for specific filetypes. Check
+the value of the 'omnifunc' option to find out if it would work.
