Vim auto complete

Question

So I know you can get Vim autocompletion with Ctrl-X, Ctrl-O but I'm wondering if you could rework it so it works with just pressing Tab (more like Textmate's snippets), or even just how I could remap it to something a bit shorter (even if I can't get fancy tab completion), as I find Ctrl-X, Ctrl-O a bit awkward.

Answer 1

I realize this question has been already answered, but you might be interested in a plugin such as SuperTab, which provides auto-completion and uses more than one type of auto-completion depending on the context and what type of completion you have been using.

Answer 2

Map Tab to Ctrl-X,Ctrl-O

:imap <tab> <c-x><c-o> 

See this page from vim-wiki for a smarter Tab completion

Answer 3
