Unable to have the reverse of Ctrl-O in Vim

Question

I want to have the reverse of

Ctrl-O

to be

Shift-Ctrl-O

The original reverse is

Ctrl-i

How can you remap the reverse of Ctrl-O in Vim to be Shift-Ctrl-O?

Answer 1

As shown in help under

:help C-o

the "reverse" of C-o is

Ctrl-I or Tab

Answer 2

Unfortunately Vim recognises Control-o and Control-O as synonyms.
There's some information here about why you can't map Control-Shift-o, but it doesn't look like it's possible.

I've upvoted Idigas answer, it's not that hard to remember Control-I.

Answer 3

Vim sees ctrl-shift-o as ctrl-o because of a limitation with terminal emulators.
