External Keyboard Helper
You can use it to remap keys into android. Please report back if it works, as I want to buy a keyboard for my tablet, but dont want to deal with useless keys
I did find this review in the UK that mentions this app does help remap and get those uesless keys working:
This high quality Bluetooth keyboard measures 28.5cm by 13cm and weighs about 360g, including the two AA batteries that are supplied with it: slightly longer than my tablet is wide, but still small and light enough to carry round.
It is solidly made, matt black metal rather than plastic, with a stylish curving shape firmly supported on rubber feet - no wobble even on slightly uneven surfaces. The slope is perfect for fast typing. The keys are low profile and short-travel, full size, responsive and quiet. No sign that any of them is likey to come loose. There is no numeric keypad, but there is a row of function keys at the top to control the tablet - search, brightness, volume, on/off etc. Battery life is claimed to be about six months as the keyboard powers down when not in use and comes back to life as soon as you press a key.
The keyboard paired with my Sony S and with my Galaxy (both Android devices) without fuss and worked immediately, although three or four key mappings needed adjusting to match the GB layout. For this the External Keyboard Helper app is highly recommended - you just press "autodetect keyboard" and everything comes right.
As other reviewers have mentioned, there is no on/off indicator. The light next to the on/off switch on the underside of the keyboard seems to show that the device is visible for pairing, rather than that it is on. Again, the External Keyboard Helper is useful here because it flashes up a discreet message when a keyboard is not detected. I only found the lack of a light a problem on one occasion - the second time I used it. The batteries supplied were flat, so nothing worked. Fortunately, before hurling it at the wall, I remembered the old principle "check the simplest explanation first".
The lack of a caps lock light I did not find a problem - this probably depends on your style of typing.
Excellent value for money.
