Function action_name 

pub fn action_name(key: ActionKey) -> String

The wire name of an action key.

The client stores this string verbatim and hands it back on invocation, so it is the only thing that has to survive the round trip. Decimal because it is the shortest form that reads back unambiguously.

REF: references/mumble/src/mumble/Messages.cpp : msgContextActionModify stores msg.action() in the menu entry’s data. REF: references/mumble/src/mumble/MainWindow.cpp : context_triggered sends that same data back as ContextAction.action.
