The bottom-line window approach was mainly for supporting Carbon
applications that cannot be moved from the WNE design model due to its
own legacy application structuring.
Since Cocoa is not based on responder message handling design, such
event handling model is unnecessary. And the user experience was
mostly accepted unfavorably by users, and, thus, Apple is moving away.
We recommend applications to integrate NSTextVIew for all text input
needs. It allows you to take advantage of future text enhancements
from the Cocoa framework transparently if applicable.
Another option is to implement the NSTextInputClient protocol for your
text editing view.
There is a new sample at /Developer/Examples/AppKit/TextInputView
coming with Xcode 3.2 showing how to interact with the protocol.
The 3rd option is to implement the bottom-line window behavior by
yourself using NSTextView.

When the application was Carbon, as I recall, I would setup a new
TSM document, and that would automatically give me the bottom-line
text input bar and I would process the input with my Carbon event
handlers. I've been doing some searching on how to accomplish the
same thing on Cocoa (enable the bottom-line text entry window and
getting events containing the Unicode text), but haven't been able
to find anything yet. It appears I might have to do something with
NSInputManager, but I haven't really seen how I can accomplish what
I want.
Not an expert in this field (though I find myself in the bowels of
the text system more and more often), but take a look at the
protocols NSText and NSTextView implement. I believe the one you
want is NSTextInput.
As for the bottom bar, that might be a legacy Carbon thing. Cocoa
input servers provide their own UI.
(But take a look at the stack trace that occurs in -keyDown:. Cocoa
creates a TSM document and does all sorts of Carbony things anyway,
but you don't get to play with them. Dunno about 64-bit, but you
might be able to cross this bridge yourself in 32 bit code.)
Some text system engineers participate on this list. Hopefully one
of them, or someone else more knowledgable than I am at the moment,
can help you out more.
Good luck!
