I have stumbled upon images of the virtual keyboard! (i think). Updates in a bit......
Yep, I've definitely found the keyboard. Only backspace, enter, globe, option, option-lock, shift, shift-lock, space, and tab keys are shown. The background is a dark gray with a gradient.
New stuff: /usr/palm/sysmgr/images/search-pill.png is the Just Type bar.
Palm put in blue and orange Palm boot logo images.
Palm calls the Quick Launch bar image "Quick Launch stash".
