This feature seems to have been out for a long time, and I want to use DEVONthink to Wikinotes, but I found that it is not like this:
Have you enabled WikiLinks in DT preferences?
If you have enabled the relevant preferences it should work (in markdown, rich text and plain text documents) as described in the user guide:
[DeepL translation of this post:
您是否在DT首选项中启用了WikiLinks？
如果您已经启用了相关的首选项，它应该可以工作（在markdown、富文本和纯文本文档中），如用户指南中所述。
DeepL translation of that part of the user guide:
输入两个开头的方括号和一个文件名的开头。然后按⌥⎋Option-Escape，显示数据库中潜在的项目匹配列表。选择一个文件，然后按回车键，完成链接。]

Yes, I turned on the preference of WikiLinks, but it seems to be mandatory automatic linking. As shown in the picture, I typed in Note1, purely in Note2 documents. I don’t know the difference between [[Note2]] and input Note2 directly , They seem to display the same effect in the preview, of course, I may not need it to force automatic linking.
Are you using markdown, plain text or rich text?
When you start typing after the opening square brackets, at least in markdown (the only one I have tested) you should be offered a list of matching records in DT. Like you, if I simply type Note in the brackets I see it underlined as a link in edit mode but it does not show as a link in preview mode (because, of course, there is no such record called simply Note in DT, in my case).

markdown, Turn on automatic linking, and if you type “[[” or not, it will link to an existing document. If it does not exist, “[[” only plays a role in creating a new document. This logical method makes me feel friction.
You have Names and Aliases enabled in Preferences > WikiLinks > WikiLinks. Disable it and the square brackets will be required.
This is very useful, but [[Using the Chinese input method to input Chinese has a problem, the following is one of my screen recordings.
I hope to check the Chinese input problem.
Thanks!
@cgrunenberg: I thought DEVONthink now allowed for typing Chinese square brackets in WikiLinks.

That’s not yet supported.
