vim CTRL-] keys isn't functioning as expected

ctrl, vim

Solution

First, use the `:verbose` command (thanks to sehe) to know who rebound your key where.

:verbose nmap <C-]>

Then, if you cannot find where your key was rebound, bind yourCtrl-] key by the original one then retry:

:nnoremap <C-]> <C-]>

For more info:

:help mapping
:help :verbose
:help :noremap

Problem

In `:help tag` it says that one can go to a tag definition using the CTRL-] keystroke. But I can't get this to work. I thought I messed some mappings with my plugins, so I cleaned `.vimrc`. But I still get cursor to a tag word (in help for example). I strike Ctrl and ] simultaneously and nothing happens. How to fix it? Or maybe I'm reading `:help` wrong?
