Search triggers too soon when entering regex

1. Enable regex mode in search.
2. Start typing F[
3. Search triggers and results in regex error:
   

Idea would be to only trigger regex search if user stops typing or if focus is left?

How do I enable regular expression? The key binding CTRL+SHIFT+F did not open global search settings window. Also, I am not able to find the toggle buttons for regex and case sensitive search.

Hi,
this is another odd thing. You first have to enable autocompletion in the preferences.
Then enter a word and then you can use the toggle buttons.

Hello,
How about instead of waiting for the user to input the text or for the search field to lose focus, we consume the exception caused due to incorrect regex?
Instead of displaying the exception we can have an incorrect syntax indicator next to the search field?

That is a good idea, display the validation indicator like its done in the preference or other places now

Does this ref #3871 (comment) somehow?
