I have a TV that runs android 2.2. It can take a USB mouse and keyboard, and I'm running the dolphin web browser on an auto-refreshed page for digital signage. Only thing is, I can't get it to zoom in or out - there is no touch (so multitouch doesn't work), and there are no +/- buttons as tehre are on some stock browsers. The stock browser doesn't work on the site in questions, and firefox won't load onto the device (it has a MIPS processor, so any app using the native SDK won't work). Any ideas?

Purchase a mouse which supports multitouch gestures (using which you zoom in or out). e.g. PadKite

If you don't want to purchase anything, just go to Dolphin's Settings, tap Lab and turn ON pinch-Zoom Button. Then, you'll find +/- clickable buttons to zoom in or out.

+1 for introducing PadKite. – Narayanan Aug 20 '12 at 10:22
