I've always had a question to ask. I finally have a chance today . Regular selective substitution?

[dublove]

I want to find "áéíóú" with regular grep and replace it with the corresponding "aeiou".

that is

á=>a

é=>e

í=>i

ó=>o

ú=>u

Do I need to do it five times?

I seem to have seen someone who can do it all at once.

Find: [áéíóú]

Replace: I don't know how to write here

Thank you~

Find: (á|é|í|ó|ú)

Change: $1

$1 represents a variable of the content found within the first parentheses. The pipe character means "or".

Obviously written without sufficient coffee. This would not work. Use find change by list as Joel suggests.

There's a script that is installed by default with InDesign called "FindChangeByList".  It does exactly what you want; it lets you stack GREP queries, so you can do five at once.

I lke Peter Kahrel's script better: https://creativepro.com/files/kahrel/indesign/grep_query_manager.html

It let's you save any query for later use and select from all the saved queries so you don't need to constantl;y rewrite the list.

1000x thanks, Peter! That is miles better than FindChangeByList. Also much better than my own folder-full-of-text-files with names like AllChineseGreps2019.txt.
