What is the list of all Android Init Language 'triggers'?

Question

In /init.rc and the other Android Init Language '.rc' files, there can be 'actions' sections that start: 'on ' to execute a sequence of commands when an event occurs in the init process. What is the list of all 'triggers'? There seem to see some specific keyword triggers, like 'boot', 'init', 'fs', 'early-init' and 'post-fs-data'. Is this a complete list of these? In the code somewhere? (In addition to the keyword triggers there are some expression triggers, see below.)

Some keyword triggers I've seen, it would be nice to know when and why they are called:

boot
early-init
init
fs
post-fs-data
charger
nonencrypted  

In addition to keywords, exmaples of expressions include:

property:ro.factory.tool=1     -- when a property is set to a value
device-added-<path>  -- Triggered when a node is added when the equipment
device-removed-<path>  -- When the device is removed to add nodes
service-exited-<name>

You can also list it on connected phone / emulator with adb:
