using copilot.vim plugin in neovim the <M+]>, <M+[> and <M+> (M stands for alt) doesn't work, the keybinding are used in insert mode and when i press alt+[ or alt+] which is the keybindings “‘ these two characters are typed, technically its the right behavior.
if so why is keybinding that? Didn't they realize this? I am using U.S. keyboard layout
I found out it's not actually Alt key; it's Meta which is not set to Alt in mac using iTerm2.
I set left-Option to Meta key in Preferences > Profiles > Keys > General > Left Option key.
