Keymap ctrl+symbol does not work

[justaskz]

Hello,

I have this helix config:

[keys.normal]
"C-/" = "toggle_comments"

When I press ctrl+/, nothing happens. I am using macos with kitty (v0.28.1) terminal. Helix version 23.05 (7f5940be).

Tried to replace / with other symbols, it does not work, only letters works.

I found this PR #4939 which should have fixed the issue, however something is wrong in my case. Helix logs are not informative. Can you give me a clue, what might be wrong?

This is helix log:

It's highly likely that something is grabbing that keybinding because I use Alt-/ for ':write' and I use kitty on Fedora Linux (and it has never failed).

Try Alt-/ for that command

[justaskz]

You are right. I did not realize that tmux can also have impact. And that was the case here. I will try to figure out, how to fix it.

[gyreas]

Does it answer your question then?

[gabydd]

What also could be happening is that tmux doesn't support the keyboard enhancement protocol as you can see from the log line
2023-05-31T12:19:00.323 helix_tui::backend::crossterm [DEBUG] The keyboard enhancement protocol is not supported in this terminal

if you try kitty without tmux you should be able to use Ctrl-/ and also not get that log line
