Unable to use ` / ~ in keybinds

[Th3T3chn0G1t]

Since ctrl+shift+z isn't available in the terminal for redo, I tried using the key directly next to it (which on my keyboard is the ` / ~ key (backtick & tilde). But when I add Ctrl-~ or Ctrl-` to the keybinds file it doesn't respond to the combo. Is my keyboard/terminal a bit screwy or are these keys just not supported?

I'm on macOS Catalina, using Terminator 2.1.1 and Micro 2.0.10.

Thanks!
