I like Jef Raskin's idea of something like a linear zooming interface (most non-programmers think linearly) per "The Humane Interface".

Imagine something like a whole website or application (or OS) "folded" into, or represented in, an accordion menu, with a fast keyboard short cut for searching "above" where you're at or "below" where you're at. Something a bit like eMacs but more graphical (eMacs content with CSS?). No documents, no pages, no slides, no "beginning" or "ending", just above or below, folded or unfolded,  + context. Folded visual content doesn't have to appear like a bar with a phrase. It could be a button bar, or just a single word or letter or icon. 

A keyboard shortcut brings your "menu bar" or "toolbar" or "navigation bar" temporarily to your cursor data entry point, to keep your locus of attention from moving too much (because you only have one of those)  ... rather than leaving what you're doing to go "top of screen" or "bottom of screen" or "left" or "right", thereby risking losing ones mental context and focus. Widgets, windows, or other visual artifacts can be placed side-by-side temporarily for comparison too by a keyboard shortcut or from a search result. This disciplines one to remember and express "what" one wants and "why", rather than dedicating brain cycles to figuring out "where" it's kept.
