Why Ctrl+; Doesn't Work in Your Terminal and How to Fix It
Recently, I needed to map a short keybinding in Neovim, but I had trouble finding a key combination that wasn’t already taken. I had the idea of using Ctrl+; , but after setting a mapping for <C-;> in my Neovim config, it didn’t work as expected! In fact, it didn’t register at all. The reason why lies deep in the history of ASCII and terminal emulators.
