Keybinding with C-/ doesn't work on Windows Terminal when SSH

[qaqland]

Summary

Want to remap ctrl+/ to toggle comments.

I add "C-/" = "toggle_comments" but it don't work.

I also tried C-/ C-."slash" C-"slash" C-"/" and nor work.

Reproduction Steps

edit config like this

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

I expected this to happen:

ctrl+/ == ctrl+c

Instead, this happened:

Bad config: TOML parse error at line 33, column 3
   |
33 | C-/ = "toggle_comments"
   |   ^
expected `.`, `=`

Bad config: TOML parse error at line 33, column 1
   |
33 | C-."slash" = "toggle_comments"
   | ^^
Invalid key code ''

Bad config: TOML parse error at line 33, column 3
   |
33 | C-"slash" = "toggle_comments"
   |   ^
expected `.`, `=`

Bad config: TOML parse error at line 33, column 3
   |
33 | C-"/" = "toggle_comments"
   |   ^
expected `.`, `=`

I test on linux (terminal foot) and windows(windows terminal) directly, "C-/" = "toggle_comments" both works!

Maybe it is caused by window terminal when SSH.

showkeys shows my linux system get this C-/ as nornmal:

qaq@lab ~> showkey -a
Press any keys, program terminates on EOF (ctrl-D):

 31 0037 0x1f
  4 0004 0x04
