copy		enter action launcher mode using current action as template

counters	display the counters of the action

details		display the details of the action, including status & times

exit		exit this mode (also works with ctrl+d)

help		show this help

investigators   print the list of investigators that signed the action

json         	show the json of the action

list <show>	returns the list of commands with their status
		<show>: * set to "all" to get all results (default)
			* set to "found" to only display positive results
			* set to "notfound" for negative results
		list can be followed by a 'filter' pipe:
		ex: ls | grep server1.(dom1|dom2) | grep -v example.net

r		refresh the action (get latest version from upstream)
