Get details of an action to run, then run it.
If Action is specified, only the parameters will be queried. This is a very useful action to assign to a home screen widget, since it allows you to easily execute any of Tasker's actions without having to set up a profile etc first.
Wait and Wait Until actions cannot be queried. As a workaround, you could query for a variable and then then Wait in the next action of the task using the variable value.
