I was going to try this out, but somehow kitty refuses to start now...
What keyboard are you using? Where is the backtick located?
To see the escape codes, you can start Vim with "vim --log logfile". The logfile will then contain the raw escape sequences that Vim gets.
Also check the output of "set termcap". Entries that matter are t_TE, t_TI and t_RK

@brammool I tried again and there is something different. The mapping works fine in kitty now, but still failed in tmux. Should I tune tmux something?
I just remember I have tested that mapping out of tmux and it is not working too. Maybe I forget to test it after I update vim to latest version.
With "vim --log logfile", it reports Ctrl+` in tmux
raw key input: "`"
and without tmux it reports
raw key input: "^[[96;5u"
And for "set termcap", both have the same values:
t_TE=^[[>4;m^[[=0;1u
t_TI=^[[=1;1u
t_RK=^[[?u

This seems like a tmux problem them.

all make sure $TERM is set properly. From the tmux manpage:
The TERM environment variable must be set to ‘screen’ or
‘tmux’ for all programs running inside tmux.
Not sure if tmux supports this key.

That looks correct, "96" is the backtick character and "5" is the Ctrl
modifier.

That looks OK for Kitty.

I am closing this, as this seems to be a kitty issue.
