* To avoid use of methods not intended to be executed via surface.execute(), the methods must be

* whitelisted here. This information is checked by ve.Surface before executing an action.
|
|
*
|
|
* If a method returns a value, it will be cast to boolean and be used to determine if the action
|
|
* was canceled. Not returning anything, or returning undefined will be treated the same as
|
|
* returning true. A canceled action will yield to other default behavior. For example, when
|
|
* triggering an action from a keystroke, a canceled action will allow normal insertion behavior to
|
|
* be carried out.
