Function do_navigate_keypress

src/interface.rs:258–264

Given a key code along with the modifier keys, the current node is moved accordingly (or value reported in some cases). `key` is the [keycode](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode#constants_for_keycode_value) for the key (in JavaScript, `ev.key_code`) The spoken text for the new current node is returned.

(key: usize, shift_key: bool, control_key: bool, alt_key: bool, meta_key: bool)

/// `key` is the [keycode](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode#constants_for_keycode_value) for the key (in JavaScript, `ev.key_code`)
/// The spoken text for the new current node is returned.
pub fn do_navigate_keypress(key: usize, shift_key: bool, control_key: bool, alt_key: bool, meta_key: bool) -> Result<String> {
    return MATHML_INSTANCE.with(|package_instance| {
        let package_instance = package_instance.borrow();
        let mathml = get_element(&package_instance);
        return do_mathml_navigate_key_press(mathml, key, shift_key, control_key, alt_key, meta_key);
    });
}

/// Given a navigation command, the current node is moved accordingly.
/// This is a higher level interface than `do_navigate_keypress` for applications that want to interpret the keys themselves.
