Why am I missing the LSP mappings gra, grn, grr and CTRL-S that neovim LSP is supposed to create automatically?

Question

According to the documentation on `:h lsp-quickstart :

Some keymaps are created unconditionally when Nvim starts:

grn is mapped in Normal mode to vim.lsp.buf.rename()

gra is mapped in Normal and Visual mode to vim.lsp.buf.code_action()

grr is mapped in Normal mode to vim.lsp.buf.references()

CTRL-S is mapped in Insert mode to vim.lsp.buf.signature_help()

But none of those are working for me, I can invoke the operations with for example :lua vim.lsp.buf.rename() but there is no grn mapping.

I'm using NVIM v0.10.0, surely those mappings should be there right?

I can create the mappings myself with

vim.keymap.set('n', 'grn', vim.lsp.buf.rename)
vim.keymap.set('n', 'gra', vim.lsp.buf.code_action)
vim.keymap.set('n', 'grr', vim.lsp.buf.references)
vim.keymap.set('i', '<C-s>', vim.lsp.buf.signature_help)

but those should be already there

These default mappings were added after release of v0.10.0, in PR #28650: add LSP default mappings (again), so it has only made it into nightly releases of Neovim so far.

If you're not ready to jump into a nightly build, you can look at the code of that PR to reproduce the mappings same as they'll make it upstream in your local setup until it makes it into a release.
