蓝色标注用英语怎么说

"Blue annotation" in English is called "blue tagging."
The origin of the phrase "blue tagging" is not certain, but it is likely that it comes from the use of the color blue to mark or highlight text or other information in a document. This practice can be done in word processing software, for example. Blue is often used as the default color for highlighting text because it is easily visible on a white background, and it is different from the black text of the document.
Here are some examples of sentences using the phrase "blue tagging" in English:
I used blue tagging to mark the important passages in the report.
The blue tagging feature in this software makes it easy to keep track of revisions.
The document was filled with blue tagging, making it difficult to read.
Here are the Chinese translation of the above sentences:
我用蓝色标注标出了报告中的重要段落
这个软件中的蓝色标注功能使得跟踪修订变得简单
这个文件上有太多蓝色标注，看起来很乱。
