I'm attempting(!) to start the sql completion tutorial on vim:

enter image description here

I've created the empty file tutorial.sql

I enter insert mode ok (press i).
Then I need to hit <C-C>s which I assume is Control+uppercase C followed by lowercase s? If I try this then I get an error message saying pattern not found, although :call sqlcomplete#Map("sqlStatement") also appears - according to the tutorial I should expect to see a list (I assume a drop down list).

Where am I going wrong?
Could changes to _vimrc be interferring with things? (suspect my error is more basic than this - like not understanding <C-C>s !)

<C-C>s is Ctrl+c followed by s. –  romainl May 19 '13 at 13:53
    
@romainl - thanks (you bored again today? ...same here!) - unfortunately I get the same response as the second screen print in OP. Let me test with my custom _vimrc off-line (i.e. I'll replace it with a default version) to see if custom mappings are interferring –  whytheq May 19 '13 at 14:29
    
oh...now I get the list!!...so a setting in _vimrc is playing with me. Also noticed in my $HOME I have _vimrc + _gvimrc...but I never change _gvimrc so I may aswell delete that file - ok? If I post my _vimrc to OP can you see the problem? (depends how bored you are?) –  whytheq May 19 '13 at 14:35
    
this line is causing the problem: au GUIEnter * simalt ~x ...I added it as someone said it would mean vim will be maximized on startup which it does - is there something else I need to add to that line so that it doesn't interfere with the sql completion ? –  whytheq May 19 '13 at 15:11
