     * The pressed keys that will trigger this keybinding.
     *
     * The `key` is made up of modifiers and the key itself.
     *
     * The following modifiers can be used:
     *
     *  | Platform | Modifiers |
     *  | :----- | :----- |
     *  | macOS, iOS |  `ctrl`, `shift`, `alt`, `cmd` |
     *  | Windows |  `ctrl`, `shift`, `alt`, `win` |
     *  | Linux, Android, ChromeOS |  `ctrl`, `shift`, `alt`, `meta` |
     *
     * If the `cmd` modifier is used, the keybinding will only apply on macOS.
     * If the `win` modifier is used, the keybinding will only apply to Windows.
     * If the `meta` modifier is used, the keybinding will apply to platforms
     * other than macOS or Windows.
     *
     * The `alt` key is the `option` key on Apple keyboards.
     *
     *
     * The following values for keys can be used:
     * * `a`&ndash;`z`, `0`&ndash;`9`
     * * `` ` ``, `-`, `=`, `[`, `]`, `\`, `;`, `'`, `,`, `.`, `/`
     * * `left`, `up`, `right`, `down`, `pageup`, `pagedown`, `end`, `home`
     * * `tab`, `enter`, `escape`, `space`, `backspace`, `delete`
     * * `f1`&ndash;`f19`
     * * `pausebreak`, `capslock`, `insert`
     * * `numpad0`&ndash;`numpad9`, `numpad_multiply`, `numpad_add`, `numpad_separator`
     * * `numpad_subtract`, `numpad_decimal`, `numpad_divide`
     *
     * The values will be remapped based on the current keyboard layout. So, for
     * example if `a` is used, on a French AZERTY keyboard the keybinding will be
     * associated with the key labeled 'A' (event though it corresponds to the
     * key labeled 'Q' on a US QWERTY keyboard).
     *
     * To associate keybindings with physical keys independent of the keyboard
     * layout, use the following keycodes:
     *
     * - `[KeyA]`&ndash;`[KeyZ]`, `[Digit0]`&ndash;`[Digit9]`
     * - `[Backquote]`, `[Minus]`, `[Equal]`, `[BracketLeft]`, `[BracketRight]`, `[Backslash]`, `[Semicolon]`, `[Quote]`, `[Comma]`, `[Period]`, `[Slash]`
     * - `[ArrowLeft]`, `[ArrowUp]`, `[ArrowRight]`, `[ArrowDown]`, `[PageUp]`, `[PageDown]`, `[End]`, `[Home]`
     * - `[Tab]`, `[Enter]`, `[Escape]`, `[Space]`, `[Backspace]`, `[Delete]`
     * - `[F1]`&ndash;`[F19]`
     * - `[Pause]`, `[CapsLock]`, `[Insert]`
     * - `[Numpad0]`&ndash;`[Numpad9]`, `[NumpadMultiply]`, `[NumpadAdd]`, `[NumpadComma]`
     * - `[NumpadSubtract]`, `[NumpadDecimal]`, `[NumpadDivide]`
     *
     * For example, using `[KeyQ]` will map to the the key labeled 'Q' on a QWERTY
     * keyboard, and to the key labeled 'A' on an AZERTY keyboard.
     *
     * As a general guideline, it is preferable to use the key values `a`&ndash;`z`
     * for keybinding that are pseudo-mnemotechnic. For the other, it is generally
     * preferable to use the keycodes.
     *
     * Consider the key combination: `alt+2`. With an AZERTY (French) layout,
     * the digits (i.e. '2') are only accessible when shifted. The '2' key produces
     * 'é' when not shifted. It is therefore impossible on an AZERTY keyboard to
     * produce the `alt+2` key combination, at best it would be `alt+shift+2`.
     * To indicate that the intended key combination should be `alt` and the
     * key on the keyboard which has the position of the `2` key on a US keyboard,
     * a key code should be used instead: `alt+[Digit2]`. This will correspond
     * to a key combination that can be generated on any keyboard.
