例如，像TextSelection . Delete这样的操作不直接从缓冲区删除文本。

For example operations like TextSelection.Delete don't directly delete text from the buffer.

我们还可以使用该命令替换给定行号的缓冲区中的文本，或者删除当前行中第一个出现的字符串。

We can also replace the text in the buffer at a given line number or remove the first occurrence of a string in the current line, using this utility.

换言之，在后续数据页被读入内存并被处理之前，它们可能已经从缓冲区中删除，并写回磁盘。

In other words, it may be removed from the buffer and written back to the disk before subsequent data pages can be read into the memory and processed.
