This is a Status Bar plugin that can be used to change between two keyboard layouts for your hardware keyboard. The package includes a Control Panel applet to select the preferred layouts. It has been tested with a USB keyboard and an N800 device.
For more information on how to enable USB host mode on N800 check this page.
The keyboard layout indicator/switcher button in the statusbar is rather ugly at the moment. It should be replaced by some kind of an icon or find a way to show the label in the right place.
