Just reproduced this on my Mac.

Also validated that the problem lies with kickstart because starting nvim --clean and Ctrl-h does indeed act as backspace as one might expect.

Interestingly, hitting Backspace performs the expected behavior of deleting the last character typed.

If you type: :map

You'll see it's already bound:

s  <C-H>       * <Lua 94: ~/.local/share/nvim/lazy/nvim-cmp/lua/cmp/utils/keymap.lua:127>
                 cmp.utils.keymap.set_map
n  <C-H>       * <C-W><C-H>
                 Move focus to the left window

Not a bug. Please see the remap in url below.

You'll see it's already bound:

@feoh it is bound in here: https://github.com/nvim-lua/kickstart.nvim/blob/773e482d4b40cec4095e4b60fbd753cb69b3f51b/init.lua#L714-L718

You can safely delete those 5 lines to make C-h work normally. That's what I did.

btw, we can just search with ctrl-f in a browser:

c-h

This has a work-around posted now. Closing.
