State
Any tool in the toolbox, these define Synfig's modes.
States can be transitory ( state_stroke is responsible only for displaying/inputting the stroke as you draw it with another tool) or they can register themselves with the Toolbox and be 'sticky'.
Action

Probably everything that can be undone.
?where is an action created / stored / executed?
Events
Synfig has an event system, using GTK's event system, I think. Snap
- Here is the gtkmm documentation. Maxy
