我找不到（不详细的）解决方案来区分新行和新段落。
据我所知，\\和\newline两者都会插入新行。但通常不建议使用第一种。
空格行会插入一个新段落。
为了分隔段落（并方便阅读），我使用以下代码，它在新段落中提供空格和缩进。
\setlength{\parskip}{\baselineskip}%
\setlength{\parindent}{15pt}%
当我想转到同一段落中的新行而不开始新段落时，就会出现问题。
这是一个类似的问题，但仍然没有详细的解决方案：用空行分隔某些段落，而其他段落则不用空行分隔？
理想情况下，我想用两个空格表示一个新段落，用一个空格表示一个新行。可以编码吗？
答案1
\\表示新行并<return><return>表示新段落，由于每个都只有两个字符，因此很难想象有更不冗长的标记可以区分这两种情况。
