ctrl+tab style tabs in gvim

Forget where i first saw this but here it is, the win7 vim path is currently

C:\Program Files (x86)\Vim

and inside this folder the file _vimrc should have these lines 

:nmap <C-S-tab> :tabprevious<cr>

:nmap <C-tab> :tabnext<cr>

:map <C-S-tab> :tabprevious<cr>

:map <C-tab> :tabnext<cr>

:imap <C-S-tab> <ESC>:tabprevious<cr>i

:imap <C-tab> <ESC>:tabnext<cr>i

:nmap <C-t> :tabnew<cr>

:imap <C-t> <ESC>:tabnew<cr> 

After this change, restart vim, hit ctrl+tab, enjoy.
