Hotkey to switch to different groups?

[revaraver]

Thanks for developing such a convenient plug-in, but I have two questions:
At 15-18 seconds into the "Toggle groups"; video in https://comfyui.ma.pe/, I see that you use some method to quickly navigate to different groups in the window. I want to know how to do this? I looked through the help and couldn't find the relevant shortcut keys.

At the same time, I don't know which hotkey is in the "Jump to assigment" video. Thank you.
