// Key bindings for Linux.

// NOTE: Avoid `Ctrl+Alt` and `Alt` shortcuts on Linux because Ubuntu based OSs have reserved system shortcuts (see GH#2370).
//       Binding shortcuts to these modifiers will result in odd behavior on Ubuntu.
// NOTE: Don't use `Ctrl+Shift+U` because it's used IBus for unicode support.
// NOTE: We can't determine the character for a dead key and no translation is provided. E.g. Ctrl+` (=Ctrl+Shift+´) on a
//       none nodeadkeys german keyboard cannot be interpreted. In general don't bind default shortcuts to characters that
//       can be produced with ^ or ` on any keyboard. --> ^, `, ", ~, ...
