You can get it even better on the 770 if you can gain root. How often do you actually need the menu hardware key? Never? Good, here we go... 1. Become root 2. Open the file /etc/matchbox/kbdconfig in a text-editor 3. The file is usually empty. Just append the line F4=next 4. Save the file and run the command matchbox-remote -keys-reload or restart the N770 5. Enjoy the easy task switching by pressing the menu key!
