I often add the following to the app delegate's
applicationDidFinishLaunching: method
[self performSelector: @selector(applicationDidBeginRunLoop:)
withObject: self afterDelay: 0.0];
applicationDidBeginRunLoop: (which you must define) will execute when
the first runloop cycle executes.
NOTE that you should (IMHO) endeavor to defer as much initialization
as possible until after the runloop has started, to avoid the annoying
bouncing-forever-in-the-dock behavior, or worse, the dreaded lollipop-
of-death.
This means that you should keep your MainMenu.nib as small as
possible, and avoid doing much in the app delegate's initialization
delegate methods beyond setting a flag to validate that they have
occurred.
Even the invocations of applicationOpenFile(s): can be deferred by
simply queuing the information in an array and processing it later
when the run loop is operational.
Nearly any application can be designed as a "one-bounce" (or less)
app, but it is best to implement that at the beginning of the design
process, not try to graft it on at the end.
Even if you have some sort of lengthy initialization process (updating
a database from a remote server, say) that must be done before the app
is "useful", you should still defer this until the runloop (and thus
the UI) is operational. The user can at least fiddle with the
preferences or adjust window size and position, (or watch a progress
panel) and you have the full capabilities of Cocoa available during
your initialization.

In what method would that need to be in to get the key on startup? I
tried without luck in init and awakeFromNib.
