Maybe the word "PATH" is too vague and too overloaded already. Why not
call it a "TOUR"?
|Client programs could add the following commands that deal with paths:
|1. Traverse current path
|2. Traverse named path
|3. Find in current path
|4. Find in named path
|5. Print current path
|6. Print named path
If I understand correctly, these commands automatically become
available to the user iff the browser detects a "Subdocument" or
"Path". It would be interesting to see how interface designers handle
this: greyed menu items? a pop-up tool bar?
|This scheme is easy to understand, easy to define, and easy to implement,

The most heavily used button in my Mosaic browser is the "Back"
button, which proves to me that this is something I've been waiting
