I can't find anymore the syntax suggestion for functions

I noticed that in the previous versions of Heidi,when you entered the name of a built-in function and you opened the parenthesis, the query editor would suggest you the names and types of arguments.
I can't reproduce that anymore.
This feature has been removed (in such a case why?) or do I make any mistake? or is there any option that must be set?
Thanks

That was never a feature of HeidiSQL. However, you can trigger the completion proposal dropdown by pressing Ctrl+Space when the cursor is over a function name.
