Explanation

VS Code (and Atom) currently use JavaScript-style regular expressions for the find/replace feature so the replace operation doesn't support switches that are available in other editors like Vim (example: \u\1) or Sublime Text (example: $1-\L$1\E).

The workflow above will achieve the same results.

When I press ALT-R it request second key or chord. Do you forget to add it or I do something wrong.
Thanks in advance

@SpirosKar, apologies for any confusion. I suspect you're on a Mac? The ALT-R keypress is for Windows and Linux, it just toggles the Regex option. You could simply select the Regex option with your mouse if it's easier.

I've also just updated the key-presses for Mac users. The key-based workflow has been tested on Windows and Linux where it works just fine. I don't have a Mac to test but the commands technically should work.

I'm on Windows, and ALT-R doesn't work for me. I did not remap that key combination. When hovering, it doesn't have a pre-defined key combination like the match case and match whole word options do.

But thanks for the overall flow.

Hmm, the purpose of ALT-R is to simply switch to regex mode. I've tested once again on Win10 (I usually use Kubuntu) and it works fine on my end, no other keypress configuration.

The keypress doesn't produce any outstanding visuals, it only selects the regex option in the Find/Replace dialog.

You made my day!
My case is the conversion of country codes into lowercase ^^
F: ([A-Z{2,}])
R: $1
F1

CTRL+ALT+ENTER

A simpler approach for me is to

1. search with regex pattern _ [a-z]
2. Do a "find all" (multi-cursor), option + enter on Mac OS
3. Delete the underscores
4. Select the letter and change to upper case using the command palette.

fantastic!
