Is there a way to use the square bracket wikilink while setting its displayed text to something differenet than the file name?
e.g. in Markdown : [some custom string](file-name)
No this is not possible. Square brackets match the exact filename. Changing the text will break the WikiLink as that’s not the name of the document.
You could perhaps try using the Names & Aliases option and add an alias to the document…
OK. Thanks.
Wikilinks based on square brackets use aliases too.
