Reading values, setting values and setting configuration options within a complex programmable apparatus is simplified, by chaining all user interaction points into a single path, cross linking portions of the main path into subpaths and providing keys that step the user according to his selection along the main path, along the subpaths, and between the subpaths. A two part display indicating the general and specific positions clarify the locations and the options available.
