If you create an action, you actually create a container, an action group as in the action group you may add (almost) as many single actions as you like. They then get executed in the sequence in the action group.
Back in the Actions dialogue, you can select with a tick in the check box those action groups that you want to have executed if you click OK. They also get executed from top to bottom. You may chance the sequence with the arrow buttons next to the list of actions.
And then there the Actions (Quick) which allow you to define and execute one action.
Just one remark on your list: the autonumbering wizard is not available in actions.
