Neovim: behavior different from vim with the same vimrc

Question

I'm using Vim and now I'm moving to NeoVim. I have configured my .vimrc so that the hotkey Control H/J/K/L moves between panels. (seamlessly between vim and tmux also).

But now when I'm moving to NeoVim, I see that Control H doesn't switch to left panel, but moves the cursor one character left. This makes me confused. I think the behavior of Neovim and vim should be the same with the same vimrc.

This is a bug from nvim and has officially discuss here:

nvim bug when pressing Control+H

Basically, that means you press Control+H, nvim will understand a backspace. So we must convert backspace again to open TmuxNavigateLeft

 <silent> <BS> :TmuxNavigateLeft<cr>
