sounds good, first thing i would try is testing proto-scripty's drag'n'drop feature, i think that is technically somelike what you want...

I'm developing a tiny little web page app which allows vehicle
inspectors to see the work last carried out on a vehicle.

The display shows the order header (who, when) and the order details (what).

At the bottom of the display, there are 3 buttons - Prev, New Search, Next.

The display is fed using AJAX, so no screen redraws and is very responsive.

Along with the Prev and Next buttons, a user can press 'P' or 'N'.

The app only has 2 input boxes and a button on the first "page"
(vehicle number and personal pin number for the inspector which is
linked to the contract(s) which are linked to the vehicle).

The main display has the 3 buttons described above and there is an
error notification "page" (vehicle not found, invalid pin number,
etc.). This page has the "New Search" button.

All working great on a desktop (IE8, Chrome and FireFox).

The app is going to be mainly used via a browser on a mobile internet
device (could be an iPhone, an iPad, or anything that has a browser).

For the touch screen systems, I'd like to be able to implement some
touch screen support.

I'd like to implement something where if the user wipes their finger
from left to right (like turning a page), then they are choosing
"Previous". If they wipe right to left, then are choosing "Next".

Are there any standards for this (OK, I'm just being hopefully) ?

Can I simulate this using Prototype?

At a guess, I think the following steps are needed ...

1 - On mousedown, record position and time.
2 - On mouseup, determine direction and duration.
3 - For a short duration and a fairly low difference in the vertical
movement, assume the intent is to trigger the page turning
4 - For a long duration or a big difference in the vertical movement,
do nothing extra.

Assuming something like the above is right, how does
highlight/cut/paste mechanism work?

For this app, the content is pretty generic and no real need for cut and paste.

Any ideas/suggestions/etc. would be gratefully received.
