排序规则是什么？How are items ranked?
按出现次数从多到少排列，次数相同时按在列表中第一次出现的先后顺序排列。占比 = 该项次数 ÷ 全部项目数（不是不同项数），最多保留一位小数（整数不显示 .0）。勾选“忽略大小写”时 Apple 和 apple 算同一项，显示为第一次出现时的写法。By count, most first; items with the same count keep the order in which they first appeared. The percentage is that item's count ÷ the total number of items (not the number of distinct items), to at most one decimal place (whole numbers show no .0). With Ignore case ticked, Apple and apple count as the same item, shown as first written.
怎样只看重复的项目？How do I see only the duplicates?
把“至少出现次数”设为 2，只出现一次的项目就不再显示；“只显示前 N 名”可以只看排行榜前几名。两者可以同时使用。项目前后的空格默认会被去掉，空行会被忽略。Set Minimum count to 2 and items that appear only once are hidden; Show top N shows just the top few. You can combine both. Spaces around items are trimmed and blank lines are ignored.
分隔符是怎么自动识别的？How is the separator detected automatically?
“自动识别”按以下顺序判断：有换行就按行分隔，否则依次检查 Tab、分号、逗号（含中文逗号和顿号）、竖线，最后才是空格。用逗号、分号或 Tab 分隔时支持 CSV 式的双引号，例如 "北京, 中国" 会被当作一项。需要其他符号时选择“自定义”，可用 \n 和 \t 表示换行和 Tab。输出沿用原来的分隔符（包括自定义分隔符和中文逗号），含分隔符的项会重新加上双引号；空行默认忽略，不算作项目。Auto-detect works in this order: if there are line breaks, each line is an item; otherwise it checks for tabs, semicolons, commas (including the Chinese comma and enumeration comma), pipes and finally spaces. With comma, semicolon or tab separators, CSV-style double quotes are honoured, so "Paris, France" counts as one item. Choose Custom for anything else; \n and \t stand for a new line and a tab. The output keeps the original separator (including a custom one or the Chinese comma), items that contain the separator are quoted again, and blank lines are ignored by default.
输入和输出是什么样的？What does the input and output look like?
例如在「列表高频项统计（找出出现最多的项目）」中输入 a,b,A，「忽略大小写」设为 勾选，输出为：a — 2 (66.7%) ⏎ b — 1 (33.3%)（⏎ 表示换行）。For example, the Find Most Popular List Items turns the input a,b,A, "Ignore case" set to on into: a — 2 (66.7%) ⏎ b — 1 (33.3%) (⏎ marks a line break).
