Yes, it was definitively to be meant as `gestures` - the N800 on-screen keyboard is not the perfect one for long posts
On an iPod you move your thumb in a semi-circolar fashion around a central button; that way you have an endless volume control/seeker. Implementing kinetic scroll on it could be great - think of a roller control, let's say for example on a VCR or a DJ cdplayer
btw, i'm feeling rather dumb after have read of +/- and center d-pad button... RTFM first

And... i tried to reproduce the bug without succes! Let's wait next reboot...
