Vim: remap key to toggle line numbering

Question

I added:

set number
nnoremap <F2> :set nonumber!

to my vimrc file. Basically what it's supposed to do is let me press F2 to toggle line numbering but it's not working. What have I done wrong?

In your .vimrc, add this:

set number
nnoremap <F2> :set nonumber!<CR>

Then pressing F2 will toggle line numbering.

This works perfectly for me, but just curious how would `nonumber!` implement the toggle function? – Wei Lin Apr 14 '15 at 00:15
With latest vim, add `:set nonumber! norelativenumber!` if you use both number and relative number. – mtk Jun 07 '16 at 07:41

This is what I use (with a different key binding):

nmap <f2> :set number! number?<cr>

The "number!" toggles the setting and "number?" reports the state.

This should be flagged as right anwser because more complete! This is the `lua` version for Neovim `vim.api.nvim_set_keymap("n", "", ":set scrollbind! scrollbind?", { noremap = true, silent = true })` – Joannes Dec 12 '22 at 08:15

nmap <silent> <F11> :exec &nu==&rnu? "se nu!" : "se rnu!"<CR>

In new vim you can set both relative number and number at once, this way:

set nu rnu

Thanks for this, is great for any kind of toggle, not just number toggling. – Hassek Jan 18 '12 at 21:38

This is one method:

map <silent> <F2> :if &number <Bar>
    \set nonumber <Bar>
        \else <Bar>
    \set number <Bar>
        \endif<cr>

(this one is nice 'cause I usually put foldcolumn in there as well)

This is another:

map <silent> <F2> :set invnumber<cr>

(direct method)

I've just used the second method you shared with us. It's the one i prefer, thank you :) – lucapette Jan 07 '11 at 09:30

The second method is far more correct and easy than anything else here (so far). It should have been a separate *and accepted* answer. – Alois Mahdal Apr 12 '13 at 11:54

I use this to toggle between relativenumber ( with current absolute line number) and no line numbering

nnoremap <silent> <leader>l :set relativenumber! <bar> set nu!<CR>
