      # Key bindings
      #
      # Key bindings are specified as a list of objects. Each binding will specify a
      # key and modifiers required to trigger it, terminal modes where the binding is
      # applicable, and what should be done when the key binding fires. It can either
      # send a byte sequence to the running application (`chars`), execute a
      # predefined action (`action`) or fork and execute a specified command plus
      # arguments (`command`).
      #
      # Bindings are always filled by default, but will be replaced when a new binding
      # with the same triggers is defined. To unset a default binding, it can be
      # mapped to the `None` action.
      #
      # Example:
      #   `- { key: V, mods: Control|Shift, action: Paste }`
      #
      # Available fields:
      #   - key
      #   - mods (optional)
      #   - chars | action | command (exactly one required)
      #   - mode (optional)
      #
      # Values for `key`:
      #   - `A` -> `Z`
      #   - `F1` -> `F12`
      #   - `Key1` -> `Key0`
      #
      #   A full list with available key codes can be found here:
      #   https://docs.rs/glutin/*/glutin/enum.VirtualKeyCode.html#variants
      #
      #   Instead of using the name of the keys, the `key` field also supports using
      #   the scancode of the desired key. Scancodes have to be specified as a
      #   decimal number.
      #   This command will allow you to display the hex scancodes for certain keys:
      #     `showkey --scancodes`
      #
      # Values for `mods`:
      #   - Command
      #   - Control
      #   - Option
      #   - Super
      #   - Shift
      #   - Alt
      #
      #   Multiple `mods` can be combined using `|` like this: `mods: Control|Shift`.
      #   Whitespace and capitalization is relevant and must match the example.
      #
      # Values for `chars`:
      #   The `chars` field writes the specified string to the terminal. This makes
      #   it possible to pass escape sequences.
      #   To find escape codes for bindings like `PageUp` ("\x1b[5~"), you can run
      #   the command `showkey -a` outside of tmux.
      #   Note that applications use terminfo to map escape sequences back to
      #   keys. It is therefore required to update the terminfo when
      #   changing an escape sequence.
      #
      # Values for `action`:
      #   - Paste
      #   - PasteSelection
      #   - Copy
      #   - IncreaseFontSize
      #   - DecreaseFontSize
      #   - ResetFontSize
      #   - ScrollPageUp
      #   - ScrollPageDown
      #   - ScrollLineUp
      #   - ScrollLineDown
      #   - ScrollToTop
      #   - ScrollToBottom
      #   - ClearHistory
      #   - Hide
      #   - Quit
      #   - ClearLogNotice
      #   - SpawnNewInstance
      #   - ToggleFullscreen
      #   - None
      #
      # Values for `action` (macOS only):
      #   - ToggleSimpleFullscreen: Enters fullscreen without occupying another space
      #
      # Values for `command`:
      #   The `command` field must be a map containing a `program` string and
      #   an `args` array of command line parameter strings.
      #
      #   Example:
      #       `command: { program: "alacritty", args: ["-e", "vttest"] }`
      #
      # Values for `mode`:
      #   - ~AppCursor
      #   - AppCursor
      #   - ~AppKeypad
      #   - AppKeypad
      #
