You can use Key Poker (
www.key-poker.com).
For each hotkey, select custom command, and write "table 1 fold", "table 2 fold" ,etc.
This will fold at the given table. However, it will not restore the focus to the previous table.
But it should restore focus to a table where an action is required.
For now, there's no command for moving back to the previous table.
Best,
