On vim's help
:help jumplist I can read:
Jumps are remembered in a jump list. With the
CTRL-Icommand you can go to cursor positions before older jumps, and back again. Thus you can move up and down the list.
However, on my terminal
mintty, Vim makes no differences between Tab and Ctrl+i.
I am wondering what is the magic to use Ctrl+i on Vim?
