public interface EditActionHandler
An EditActionHandler is a class that handles common actions you'd find under an "edit" menu, like cut, copy, paste,
and delete. This is used so that all workspaces and focused frames can share the same GUI elements for these actions,
and simply 1) handle the actions and 2) tell the system whether or not they are currently enabled.
