Describe the bug

I am trying to set coc.nvim for the first time, and i am watching many configs and trying to reproduce them. I want the suggestions box to have the first suggestion selected, and i want to be able to autocomplete using Ctrl+Space.

Reproduce the bug

When i did :verbose inoremap there was nothing attributed to it. And not that i configurated the coc.vimfile, it returns me

i  <C-Space>   * coc#refresh()
        Last set from ~/.config/nvim/plug-config/coc.vim line 43

And i did source $HOME/.config/nvim/plug-config/coc.vimon my init.vim

So basically is all set correctly. But ctrl+space does nothing, it doesnt autocomplete when i start typing something and the suggestions box come up. And sometimes what it does is skip a line.

Also, on my coc.vim file, i have the basic configuration file from the README.

Could be your terminal not send that key codes to vim, use other key mapping instead,

I use alacritty, there are no keybindings assigned to Ctrl+Space in that.

[chemzqm]

Debug your vim, doesn't seems issue of coc.nvim

[hrqmonteiro]

Is not an issue on my shell, you can check here if you want, neither on my vim, as you can see, i am able to pass a ctrl+space for other things in vim and it works, as i stated there.

It just won't work with coc and the coc#refresh command.

[chemzqm]

coc#refresh() does trigger completion only.

@hrqmonteiro Out of curiosity, have you tried sourcing your ~/.vimrc after vim is started?

Hi, i actually use Neovim, i don't have a .vimrc file.

[make-github-pseudonymous-again]

@hrqmonteiro Ok. I use vim. I tried to use the <c-@> shortcut but somehow it only works when I source the config file after vim has started. Before sourcing it I can see that the mapping is there, and that keystrokes get registered by vim (^V^@ in insert mode), but the mapping does not "work".

c-space does not work for me on either windows terminal nor wezterm under windows, though weirdly it works on kitty on linux

i too have the issue, i disabled all my plugins, and attempted it, and then reinstalled coc-tsserver. I think it may be with neovim itself somewhere.

@make-github-pseudonymous-again this method worked for me without the sourcing
