Backtick symbol on Xiaomi keyboards

here is a backtick symbol

`

on linux the keyboards for xiaomi pad 5 and pad 6 can't type backtick by default

two possible solutions are

1. copy and paste the symbol every time you need it
2. use third-party keyd tool to map this symbol to alt+esc

install keyd

sudo dnf copr enable -y alternateved/keyd
rpm-ostree install keyd

reboot your device

systemctl reboot

write keyd config

[ids]
*

[alt]
esc = `

write this config to /etc/keyd/default.conf

enable keyd

sudo systemctl enable --now keyd

now you can type backtick with alt+esc
