First, if that isn't clear to you, <C-i>
is the same as <Tab>
; unfortunately, you cannot map them separately.
You screenshot shows that snipMate has grabbed <C-i>
in visual and select mode; it needs those mappings to jump to the next snippet tab stop. You can change that by editing the snipMate file, but these mappings do not interfere with the normal-mode <C-i>
mapping that you're concerned about.
In normal mode, you've remapped <C-i>
/ <Tab>
to gt
in your .vimrc
; you need to re-assign or remove that to get back the original <C-i>
command.
