我有一个Microsoft Word加载项,可以在文本中找到相似的单词(但是当我单击一个按钮时！)

我的问题是：如何在用户输入单词时调用函数？

换句话说,当用户键入以获取当前单词并处理它并获得类似单词时,我想要一个类似“TextChange”或“Keypress”的事件.

有些事情像这样：

private void TextChangeEventOfCurrentActiveDocument(object sender, System.EventArgs e)
{
    ...
}

任何其他想法,我可以得到用户输入的新单词？

谢谢.

解决方法:

最后,经过很长一段时间,我使用Windows钩子创建了这个加载项.

(特别感谢@Reg编辑)

在这里,我写的整个代码,这对我来说很好. (删除了一些可选的代码部分.)
