背景说明
经常看英文资料的同学可能会遇到：遇到一段英文，想看他的中文，通常需要复制后再粘贴到翻译软件里，步骤多非常麻烦。如果能有什么工具，可以一键自动翻译而不需要手动打开翻译软件，那就很方便了。
使用步骤
制作了一个常驻后台的剪切板翻译助手小工具。使用步骤如下：
-
启动工具后，会自动监听按键
-
工具会自动添加托盘图标，右击图标可选择退出程序
-
鼠标选中英文文本 ，按下Ctrl + C + C（不松 Ctrl，连续按两次 C）
-
触发工具自动读取剪切板英文内容，并进行英译中
-
弹出一个翻译窗口：
-
上半部分显示原文（可编辑）
-
下半部分显示翻译结果（可编辑）
-
底部支持重新翻译、复制翻译
-
-
按Esc键可以关闭翻译窗口
工具演示
1、双击打开翻译小助手.exe
2、任务栏显示小图标表示启动成功
3、选中英文
4、按下Ctrl+C+C，弹出翻译窗口
5、关闭翻译窗口，回到步骤3，重复使用
6、右击图标可退出
