CEFSHARP是否可以进行CTRL + F样式搜索？我知道id必须手动创建对话框，但是如何获得实际执行的操作？如果我键入“ test”，它将在chrome中工作，并突出显示所有“ test”。
我已经有一个键盘挂钩设置，因此我可以很容易地实现CTRL + F热键，但是我不确定实际进行搜索的方式。
如果有帮助，这里是热键键盘挂钩：
list_a要使用此挂钩，请在您的public class KeyboardHandler : IKeyboardHandler

对象上使用ChromiumWebBrowser的公共属性，只需将其设置为KeyboardHandler，其中new KeyboardHandler()是上面的类代码
