hmm, the short version of the answer is - read the Treo 600 Developer's Guide, which is available for download if you are member of the palmOne's PluggedIn developer program (which is separate from the palmSource's developer program). :-)
In the guide you will find the API functions (FrmSetNavFocus, FrmSetNavEntry, etc.) to set the focus mode and to adjust the navigation order. As recommended there, the best way to do it is to create navigation map resources for your forms. Alternatively, you can rely on the default navigation order, which Treo will compute for you, and just adjust with the API functions the things that you don't like. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
