My goal: open Yakuake or Tilda terminal with Super + Grave (backtick, tilde, `) shortcut in Gnome. What I could achieve is only holding Super + pressing Grave twice.
A little background. By default Super + Grave is a shortcut for /org/gnome/desktop/wm/keybindings/switch-group
So I disabled it in DConf editor.
Then when I just press Super + Grave (`) once, I just see ` symbol in Tilda, while Yakuake shows s` somehow (yes, with additional s letter). But pressing Grave twice works (though additional ` symbol gets typed, that is annoying).
What's interesting, when I install Drop Down Terminal Gnome Extension and set Super + Grave shortcut it works perfectly. But Drop Down Terminal is too simple for me.
I use Gnome 3.32 and International English layout + Russian keyboard layout.
This is easy to fix. You need to get the Gnome Tweak Tool and navigate to the keyboard settings. On Cinnamon, you can do the same by opening Settings->keyboard->Layouts->Options. You should see something like this:
Open the "Alt/Win key behavior" and change it from "Default" to "Hyper is mapped to Win":
That should solve the issue.
