不,我不认为教程这么说。我认为您指的是SEARCHING部分和此文本:
>> Type C-s again, to search for the next occurrence of "cursor".
>> Now type `<DEL>` four times and see how the cursor moves.
If you are in the middle of an incremental search and type <DEL>, the
search "retreats" to an earlier location. If you type <DEL> just
after you had typed C-s to advance to the next occurrence of a search
string, the <DEL> moves the cursor back to an earlier occurrence. If
there are no earlier occurrences, the `<DEL>` erases the last character
in the search string. For instance, suppose you have typed "c", to
search for the first occurrence of "c". Now if you type "u", the
cursor will move to the first occurrence of "cu". Now type <DEL>.
This erases the "u" from the search string, and the cursor moves back
to the first occurrence of "c".
A<DEL>
不向后搜索。它从搜索字符串中删除一个字符,然后搜索移动到结果字符串的前一个命中(仅)。但第一个<DEL>
afterC-s
不会改变搜索字符串。它只是移动到上一个命中(仅)。
教程文本并没有错,尽管它可能有点难以阅读。如果你有改进它的建议,或者只是想让 Emacs Dev 知道你发现它不清楚,请使用M-x report-emacs-bug
