Shortcut to branch off

I would like to have a shortcut to branch off to another model from the latest message.
I was thinking in something like:

• Press shortcut

• Branch off menu show up on the latest message/reply

• Use arrow keys to select model (would be nice if the favorite one show up first)

• Press enter to select the model to branch off (would be nice if the cursor is already on the new chat to start timing without leaving the keyboard)
