 helpTextForKey: aKey

(comment from inherited method)
flyByHelp interface:
return some short help text for a key.
Key is the symbol associated with some widget or menu item.
(from my helpSpec);
Return a language variant (if available).
Special: with CTRL, show how it is generated (the helpKey or action block)

 postBuildWith: aBuilder

(comment from inherited method)
this is sent after an interface is built from a spec,
but only iff the appModel is not the same as the topView's app
(i.e. if it is not a build for the same appModel again).
In that case, postBuildAsSubcanvasWith is invoked.
Can be redefined in subclasses for additional setup after
the view has been built, but not yet opened.
