I think it should be possible to remove the search limit if the search term start with a configurable element in a list.
eg: $:/config/Search/PrioritySymbols or something similar, which may contain a list of symbols,
that will ignore the $:/config/Search/MinLength setting.
IMO This one would also make a good “feature request” at GitHub. BUT – The search dropdown is already super complex code. So imo it will not be a quick fix ![]()
So the cheatsheet plugin may be a short term workaround with the new Wikitext Symbol table
