Mapping a default key binding in vim

Question

I want to remap Ctrl-] which is used for jumping to the tags to another key binding.

These mappings work:

:map <F2> <C-]> :map <A-1> <C-]>

But this mapping doesn't work:

:map <C-1> <C-]>

What might be the reason for this?

What does Vim show when you type <C-v><C-1>? I think it must be possible to map this in Gvim, but I do not think that you will be able to map this in Vim. — ZyX

And, it is good to use *noremap instead of *map unless you know that you definitely need to use *map. It can save your time because you may run into the situation when your mapping does not work as expected because some characters are remapped somewhere else. — ZyX

Failed to map <C-1> in gvim-7.2.303, typing <C-1> just produces 1. — ZyX

I believe the problem is that Ctrl+1 is not a valid ASCII character. From this list

(search for "^^" or "^@" to see the table )

you will see that there are several keybindings such as ctrl+@ Ctrl+^ and Ctrl+]

so you are not actually calling Ctrl+2 or Ctrl+6 but their ASCII equivalents.

VIM is designed to be lightweight and fairly platform independent. so if it isn't in the list of ASCII characters you cannot make a binding to it.

It might be getting trapped/filtered by your OS. If you check the mappings, is it listed?

Yes I can see it in the mappings list.
