IPad – How to use a detached keyboard with the iPad Pro so I can draw and use quick keys with it flat

From a FAQ of Smudge Guard:

Unfortunately, the current SG gloves are not compatible with the iPad at all. The SG glove does not prevent detection on the iPad. :(

However, please note that recently, two other customers of mine bought the SG glove and tested it while sketching on the Autodesk Sketchbook Pro. They said it did not prevent accidental strokes with their palm because the material/fabric was not thick enough. But cleverly, my two other customers then tried slipping in a microfiber cloth, (folded in half) into the side of the glove. The microfiber they used, were those little rectangular shaped cloths that are made to clean eyeglasses. They inserted it into the glove (where the edge of the hand is) and they said it worked! The iPad didn't detect the side of their hand.

There is also an info they started working on a fully-iPad compatible glove. Microfiber option could work with any thin glove, perhaps.

KeyRemap4MacBook also supports device-specific settings:

You can see the vendor and product IDs from EventViewer.app. If it can't remap any keys on the external keyboard, try uninstalling other keyboard or HID drivers.

See the source for the key code values and predefined settings.
