如果我使用终端并输入一行文本命令，是否有热键或任何方法来清除/删除该行?
例如，如果我当前的行/命令非常长，比如:
> git log --graph --all --blah..uh oh i want to cancel and clear this line <cursor is here now>
是否有一个热键或命令可以从上面切换到:
>
?
通常我会按↓键，如果我的当前行是一个全新的历史记录，这将清除它。但如果我通过↑键浏览我的命令历史记录并开始编辑或使用这些命令，↓只会将提示符更改为历史记录中下一个最新的命令，所以除非我多次按↓，否则它不会在这里工作。

Ctrl+u:移动到你的行开始到一个环形缓冲区 Ctrl+k:移动到你的行的末尾到一个环形缓冲区 Ctrl+w:移动字符和(多个)字左从你的光标到一个环形缓冲区 Ctrl+y:插入环缓冲区中的最后一项，然后使用Alt+y旋转环缓冲区。按多次以继续“上一个”进入环缓冲区。
