You can? Can you tell me more about this? I'll read the developer docs
myself when I have the time, but at the moment I'm busy with Cocoa and

Yes, it really does. This idea was sitting in the back of my mind since
I got my Palm a few years ago. And apparently I'm not the only one
thinking about it:

The WikiWikiWeb also has some insights on links in both directions and
version management:

And there's of course Xanadu, the project that started it all

No, inverse is already used for "selected". Why not underline the word?
That's already standard in html, so people are used to it.

Hm. Adding this feature would clutter the interface without need. But
it's not really necessary. You could handle this with additional links
on the linked page, I think.

Don't. It's just getting interesting :)

Maybe it's getting a bit OT, but IMO this would be a feature that would
really go beyond paper emulation. Go ahead and flame me for this, but I
still don't see a good reason why I shouldn't just take my notes on a
paper notepad instead of a Newton.

Another program that I always missed on handhelds is a mathematics
notebook with an integrated computer algebra system (for solving
equations, plotting graphs etc) and typesetting (in TeX quality). This
includes recognition of all the mathematical symbols as well as a sense
for their placement.
