Renaming: Control keys for moving filename segments with CTRL + [ or ]?

In one of Leo's videos, embedded in one of the post on the forum, he showed a hotkey function example for moving filename segments in the Advanced Rename Dialog and in a Lister. This functionality allows you to position the cursor in the filename and use the CTRL + [ or ] hotkeys control keys to shift filename segments.

Somehow along the way I seemed to have lost these hotkeys control keys I setup, they vanished from Keys tab in the Customize panel. I would like to recreate them but after quite a bit of searching on the forum I have not been able to find Leo's post with the particular video.

Edit: The post I was looking for: Examples: Custom Rename Keys (Opus 13)

Any guidance on where to locate this information would be greatly appreciated.

You are looking for Preferences / File Operations / Renaming Files / Control Keys.

Merci beaucoup @lxp! Nothing vanished, the set control keys are both still there, as you probably already expected. They were just not working as they should and I started searching in the wrong places. "You're more likely to find what you're looking for if you know where to look." :upside_down_face:

...and I think it's about time for me to replace my left CTRL keyboard switch...
