Haven't seen this posted anywhere, some might find it useful. The flatness of the keys on the physical keyboard makes it hard to type without hitting incorrect or multiple keys. What I have done to prevent this is I have cut some small squares out of the scraps leftover from my InvisibleShield installation. I have cut the squares small enough so you can feel a gap between the keys. I used a toothpick to apply the small squares, no water was needed. I think this may work better with some small round stickers with tapered edges, but they would have to be manufactured for this purpose. Edit (11/22) Added picture, you can see the space you will feel between the keys. I haven't had and problem with the sliding, the material is too thin to interfere. Edit (11/23) New picture, used leather punch tool to make round stickers. It still doesn't look as nice as the bare keyboard, but much better than it did. This has made the keyboard much more useful to me.
