Thanks for the fast reply...
Yes you are right in everything to the extent that the game is very playable on the Z thanks to the keyboard

... although turned 90 degrees
But to the movement problem, I think in the long term this has to be resolved in a way, the problem is that using the pad is rather clumsy, its even clumsier
if the keyboard is also open. The problem with this is that I don´t know if the zaurus can stand a long pad usage with an open keyboard
a better solution might be to use a combination of one of the predefined buttons and the cursor (aka stylus) for movement, the other standard buttons also might be usable for the 3-4 needed standard keys
Another solution for the movement problem might be the way the documents are handled ... tab a special place for a longer time and movement is activated (not good for travelling but if you only move within the screen its perfect)
Another even better solution might be to use the double tab for movement and the long tap as double click replacement for items (would be very conform on how the Z handles it)
