Yes. The first is bound to `vimpulse-jump-forward', the second to
`indent-for-tab-command'. And when I jump back three times with
C-o C-o C-o, I can jump forwards with C-i C-i C-i, but not with
<tab> <tab> <tab>.

Spartan. :)

I'm attaching a 11 kB PNG file showing Emacs under cmd.exe.
Let's see if it gets through.

And sure enough, Vim does not. Vim treats <Tab> and CTRL-I as the same
key. In vanilla Vim, you can go to a newer jump position with <Tab>;
and in my Vim, where I rebind <Tab> to <Esc>, I can exit Insert mode
with CTRL-I.
