Document <space>y for copy-paste?
After talking with a friend about a different editor, I found out by accident that <space>y does the same copy-paste as "+y. (A clipboard like xclip must be installed already)
Apparently this comes from telescope.nvim. Opening this issue to get down this nifty trick.
Are you sure telescope.nvim sets this keybind? I couldn't grep for it, and it wasn't in <leader>sk (show keymaps) either.
I don't know. I thought telescope.nvim set the space bar keybind.
I think you need to execute nvim --clean -u contrib/minimal.lua with this file: https://github.com/neovim/neovim/blob/master/contrib/minimal.lua along with the possible plugin to confirm which one caused this issue.
