Remapping crtl+backspace to delete previous word in insert mode!

[Anirudh Singh Bhadauria]

Problem - Remapping crtl+backspace to delete previous word in insert mode! 

I am finding it really hard to do this, I have tried many combinations but it just doesn't work.

(however, I was able to remap just backspace to delete the previoius word, but that's not practical) Therefore, If anybody has a solution, that would be great! 

Remapping combinations that I tried so far, 

-- vim.keymap.set("i", "<C-BS>", "<C-W>", { desc = "delete whole word" })
-- vim.keymap.set("i", "<C-W>", "<C-\\><C-O>dB", { noremap = true, silent = true })
-- vim.keymap.set("i", "<C-W>", "<C-\\><C-O>db", { noremap = true, silent = true })
-- vim.api.nvim_set_keymap('i', '<BS>', '<C-\\><C-O>db', { noremap = true, silent = true }) (remaps backspace to delete the previoius word)

Thank you, 

Anirudh

Are you trying this in a terminal or in the gui. Ctrl-Backspace may not
universally work.

This is neovim config. Are you using Neovim?

I've this mapping for command-line editing mode that works in vim running in
gnome-terminal:

" Ctrl-Backspace deletes word backwards
cnoremap <C-BS> <C-W>
" (gnome-terminal sends ^H for ctrl-backspace)
cmap <C-H> <C-BS>

in my .vimrc. This config also works fine for nvim in gnome-terminal.
I haven't gone out of my way to test whether the same mapping will work
in insert mode, but I don't see any reason why it wouldn't.
