I have made these quick observations about BlackBerry Bold Browser: Spin trackball
Move mouse cursor. Diagonal movements work properly, unlike in Opera Mini. Faster trackball spins move the mouse pointer incredibly fast (pointer acceleration). It finally feels like a true mouse pointer now, and feels much better than previous mouse pointer in Desktop browsing mode on Pearl and Curve. Click trackball
Zoom into webpage (until fully zoomed in) ALT + Click trackball
Zoom out of webpage SHIFT + Spin trackball
Fast panning around the web page Adjust mouse pointer speed
I noticed that it was a little obscure to adjust the mouse pointer speed -- it is adjusted in Settings -> Screen/Keyboard (I use 90% sensitivity for horizontal and vertical, I prefer this over the 70% default) Adjust the amount of zooming before you can edit textboxes, etc
Go into Browser Options, and change font size to a smaller font size such as about 3 or 4. That way, you don't have to zoom in as much before you're allowed to edit text in textboxes. You are allowed to use font sizes as small as 1.
and then later trying to access BlackBerry Bold's menus. With this page, it grinds to a laggy crawl with the spinning watch (the Bold equivalent of the hourglass)
